SI-7582 Only inline accessible calls to package-private Java code

Two problems here.
The inliner was using `isPrivate` / `isProtected` to determine access.
The fallthrough considered things to be (bytecode) public. This is okay
in practice for Scala code, which never emits package private code.
Secondly, we must check accessibility of the called symbol *and* its
owner. This case is tested in `run/t7582b`.
This commit tightens the check for Java defined symbols: a) check the owner,
and b) don't assume that `! isPrivate` is accessible.

The `privateWithin` attribute of Java companion module classes was
correctly set under joint compilation (ie, when using JavaParser),
but not under separate compilation.
This commit remedies this. The test covers variety of Java symbols.

SI-7571 Allow nesting of anonymous classes in value classes

5d9cde105e added deep prohibition of nested classes within
a value class. This has the undesirable side effect of
prohibiting partial functions literals in method bodies
of a value class.
The intention of that prohibition was to avoid problems
in code using Type Tests, such as:
class C(val inner: A) extends AnyVal {
class D
}
def foo(a: Any, other: C) = a match { case _ : other.D }
Here, the pattern usually checks that `a.$outer == other`.
But that is incongruent with the way that `other` is erased
to `A`.
However, not all nested classes could lead us into this trap.
This commit slightly relaxes the restriction to allow anonymous
classes, which can't appear in a type test.
The test shows that the translation generates working code.

Specialization rewires class parents during info transformation, and
the new info then guides the tree changes. But if a symbol is created
during duplication, which runs after specialization, its info is not
visited and thus the corresponding tree is not specialized.
One manifestation is the following:
```
object Test {
class Parent[@specialized(Int) T]
def spec_method[@specialized(Int) T](t: T, expectedXSuper: String) = {
class X extends Parent[T]()
// even in the specialized variant, the local X class
// doesn't extend Parent$mcI$sp, since its symbol has
// been created after specialization and was not seen
// by specialzation's info transformer.
...
}
}
```
We can fix this by forcing duplication to take place before specialization.

GenBCode is a drop-in replacement for GenASM with several advantages:
- faster: ICode isn't necessary anymore.
Instead, the ASTs delivered by CleanUp (an expression language)
are translated directly into a stack-language (ASM Tree nodes)
- future-proofing for Java 8 (MethodHandles, invokedynamic).
- documentation included, shared mutable state kept to a minimum,
all contributing to making GenBCode more maintainable
than its counterpart (its counterpart being GenICode + GenASM).
A few tests are modified in this commit, for reasons given below.
(1) files/neg/case-collision
Just like GenASM, GenBCode also detects output classfiles
differing only in case. However the error message differs
from that of GenASM (collisions may be show in different order).
Thus the original test now has a flags file containing -neo:GenASM
and a new test (files/neg/case-collision2) has been added
for GenBCode. The .check files in each case show expected output.
(2) files/pos/t5031_3
Currently the test above doesn't work with GenBCode
(try with -neo:GenBCode in the flags file)
The root cause lies in the fix to
https://issues.scala-lang.org/browse/SI-5031
which weakened an assertion in GenASM
(GenBCode keeps the original assertion).
Actually that ticket mentions the fix is a "workaround"
(3) files/run/t7008-scala-defined
This test also passes only under GenASM and not GenBCode,
thus the flags file. GenASM turns a bling eye to:
An AbstractTypeSymbol (SI-7122) has reached the bytecode emitter,
for which no JVM-level internal name can be found:
ScalaClassWithCheckedExceptions_1.E1
The error message above (shown by GenBCode) highlights
there's no ScalaClassWithCheckedExceptions_1.E1 class,
thus shouldn't show up in the emitted bytecode
(GenASM emits bytecode that mentions the inexistent class).

SI-7590 TreeSet should fail fast if Ordering is null

While migrating scala.tools.nsc.util.TreeSet to
scala.collection.mutable.TreeSet, I messed up initialization order
and realized that TreeSet accepts null as an Ordering and only fails
much later.
This change makes mutable.TreeSet and immutable.TreeSet fail
immediately.

This performs method specialization inside a scope other than a {class,
trait, object}: could be another method or a value. This specialization
is much simpler, since there is no need to record the new members in
the class signature, their signatures are only visible locally.
It works according to the usual logic:
- we use normalizeMember to create the specialized symbols
- we leave DefDef stubs in the tree that are later filled in by tree
duplication and adaptation
The solution is limited by SI-7579: since the duplicator loses the sym
annotations when duplicating, this expansion and rewiring can only take
place in code that has not been subject to duplication. You can see the
test case for an example.

SI-7600 [Avian] Skip tests r/stream_length and r/t4294

| | | | | | | | | |
The issue is that Avian's GC is currently not precise enough to
determine the exact lifetime of each local/stack reference, and
therefore considers the this reference to be reachable in situations
where it could have been collected.
This can cause issues (as seen in run/stream_length and run/t4294:
`java.lang.OutOfMemoryError`) if code relies on the garbage collection
of these values to keep memory consumption constant.
This commit simply skips these two tests on Avian until the GC
implementation is fixed.

It regressed in fada1ef6b#L4L614. Partially reverting just
this change restores the correct behaviour:
```
- if (sym.isStable && pre.isStable && !isByNameParamType(tree.tpe) &&
+ if (treeInfo.admitsTypeSelection(tree) &&
```
This patch embeds the check for by-name parameter types into
`TreeInfo.isStableIdentifier`. That code already checks for
`Symbol#isStable`, which exludes direct references to by-name
parameters. But the additional check is required to deal with
by-name parameters in function types, e.g `(=> Int) => Any`.
Open question: should we go further and embed this check in `isStable`?
Currently:
final def isStable = isTerm && !isMutable && !(hasFlag(BYNAMEPARAM)) && (!isMethod || hasStableFlag)
Such function types are an underspecified corner of the language,
albeit one that is pretty useful writing, for example, in the
signature of a lazy foldRight that can operate over infinite
structures:
def foldRight[A, B](fa: F[A], z: => B)(f: (A, => B) => B): B
The next commit subjects them to a little testing.

In the same vein as SI-6994, we have to be careful not to warn
about synthetic code. In that case, the spurious warnings came
because we warned in the typechecker, which was also called in
erasure. In this case, we are issuing the warning in Uncurry,
so we must be mindful of the pattern matchers translations of
non-trivial catch patterns, which look like:
case (ex8 @ _) => {
<synthetic> val x5: Throwable = ex8;
case11(){
if ({
case14(){
if (x5.$isInstanceOf[NullPointerException]())
matchEnd13(true)
else
case15()
};
case15(){
if (x5.$isInstanceOf[RuntimeException]())
matchEnd13(true)
else
case16()
};
case16(){
matchEnd13(false)
};
matchEnd13(x: Boolean){
x
}
})
This commit detects that `ex8` is synthetic and disables the warning.

`originalInfo` can return null for stub symbols; deal with that
as we used to before a regression in 016bc3db.
After this change, we can once again delete A_1.class and still compile
code instantiating B_1. (A_1 is only referred to in a method signature
of B_1 which is not called from our code.)

Increase eligibility requirements for implicit conversions,
such that T => U is ineligible if
T <: Null <or> AnyRef <: U
This has the salutary effect of allowing us to ditch 16
ridiculous implicits from Predef, since they existed solely
to work around the absence of this restriction.
There was one tiny impact on actual source code (one line
in one file) shown here, necessitated because the literal null
is not eligible to be implicitly converted to A via <:<.
def f[A](implicit ev: Null <:< A): A = null // before
def f[A](implicit ev: Null <:< A): A = ev(null) // after
As impositions go it's on the tame side.
