Now both of the overloaded variants have a parameter list.
This seems to make type inference happier. Or it makes someone
happier.
The user is unaware whether `subsets()` takes a default arg.
But happily, empty application still kicks in.

Calling `findMember` in the enclosed test was calling into
`NonClassTypeRef#relativeInfo` an exponentially-increasing number
of times, with respect to the length of the chained type projections.
The numbers of calls increased as: 26, 326, 3336, 33446, 334556.
Can any pattern spotters in the crowd that can identify the sequence?
(I can't.)
Tracing the calls saw we were computing the same `memberType`
repeatedly. This part of the method was not guarded by the cache.
I have changed the method to use the standard idiom of using the
current period for cache invalidation. The enclosed test now compiles
promptly, rather than in geological time.

Generate alphanumeric values by taking random element of string
containing all alphanumerics.
Instead of generating nextPrintableChar then filtering for
alphanumerics, we can just take from a string containing all
alphanumerics. This provides a significant performance improvement.

Members of value classes are moved over to the companion object early.
This change ensures that closure classes nested in value classes
appear that way to Java reflection.
This commit also changes the EnclosingMethod attribute for classes
(and anonymous functions) nested in anonymous function bodies. Before,
the enclosing method was in some cases the function's apply method.
Not always though:
() => { class C ... val a = { class D ...} }
The class C used to be nested in the function's apply method, but not
D, because the value definition for a was lifted out of the apply.
After this commit, we uniformly set the enclosing method of classes
nested in function bodies to `null`. This is consistent with the
source-level view of the code.
Note that under delambdafy:method, closures never appear as enclosing
classes (this didn't change in this commit).

Trait implementation classes and specialized classes are always
considered top-level in terms of the InnerClass / EnclosingMethod
attributes. These attributes describe source-level properties, and
such classes are a compilation artifact.
Note that the same is true for delambdafy:method closure classes
(they are always top-level).

| | | | | | |
| | | | | | | |
Private trait methods are not added to the generated interface, they
end up only in the implementation class. For classes nested in such
methods, the EnclosingMethod attribute was incorrect.
Since the EnclosingMethod attribute expresses a source-level property,
but the actual enclosing method does not exist in the bytecode, we
set the enclosing method to null.

This change fixes both GenASM and GenBCode, except for the change
to renaming in LamdaLift mentioned below.
The reason for an inconsistent EnclosingMethod attribute was the
symbol owner chain. Initially, closure class symbols don't exist, they
are only created in UnCurry (delambdafy:inline). So walking the
originalOwner of a definition does not yield closure classes.
The commit also fixes uses of isAnonymousClass, isAnonymousFunction
and isDelambdafyFunction in two ways:
1. by phase-travelling to an early phase. after flatten, the name
includes the name of outer classes, so the properties may become
accidentally true (they check for a substring in the name)
2. by ensuring that the (destructive) renames during LambdaLift
don't make the above properties accidentally true. This was in
fact the cause for SI-8900.

For local definitions (eg. in a block that is an argument of a method
call), the type completer may have a silent context. A CyclicReference
is then not thrown but transformed into a NormalTypeError. When
deciding if 'x = e' is an assignment or a named arg, we need to report
cyclic references, but not other type errors. In the above case, the
cyclic reference was not reported.
Also makes sure that warnings are printed after typing argument
expressions.

SI-9097 Remove spurious warning about conflicting filenames

| | | | | | | |
Uses the same idiom in `Flatten` and `LambdaLift` as is established
in `Extender` and (recently) `Delambdafy`. This avoids any possibility
of adding a member to a package twice, as used to happen in SI-9097.

When using delambdafy:method, closure classes are generated late.
The class is added to a map and integrated into the PackageDef in
transformStats.
When declaring a package object, there are potentially multiple
PackageDefs for the same package. In this case, the closure class
was added to all of them. As a result, GenASM / GenBCode would run
multiple times on the closure class. In GenBCode this would trigger
a warning about conflicting filenames.

SI-9041 Avoid unreported type error with overloading, implicits

| | | | | | | | |
If `qual.foo(args)` fails to typecheck, we fall back to
`ImplicitView(qual).foo(args)`. However, if the original type error
stemmed from an overload ambiguity, the tree `Select(qual, 'foo')`
holds onto an error symbol. The fall back attempt just returns an
`Apply` tree containing the erroneous qualifier, as it does not
want to issue cascading type errors.
This commit replaces the error symbol with a `NoSymbol`, which
triggers the second try typechecking to perform overload resolution
again.
A more principled fix might be to more pervasively duplicate trees
before mutating their types and symbols, that this is beyond the
scope of this bug fix.

The pattern matcher needs to substitute references to bound
variables with references to either a) synthetic temporary vals,
or to b) selections. The latter occurs under -optimize to avoid
to be frugal with local variable slots.
For instance:
```
def test(s: Some[String]) = s match {
case Some(elem) => elem.length
}
```
Is translated to:
```
def test(s: Some[String]): Int = {
case <synthetic> val x1: Some[String] = s;
case4(){
if (x1.ne(null))
matchEnd3(x1.x.length())
else
case5()
};
case5(){
matchEnd3(throw new MatchError(x1))
};
matchEnd3(x: Int){
x
}
}
```
However, for a long time this translation failed to consider
references to the binder in types. #4122 tried to address this
by either using standard substitution facilities where available
(references to temp vals), and by expanding the patmat's
home grown substitution to handle the more complex case of
referencing a selection.
However, this left the tree in an incoherent state; while it
patched up the `.tpe` field of `Tree`s, it failed to modify the
info of `Symbol`-s.
This led to a crash in the later uncurry phase under
`-Ydelambdafy:method`.
This commit modifies the info of such symbols to get rid of stray
refeferences to the pattern binder symbols.
