Use `ant -Dstarr.version="2.11.0-M2" -Dlocker.skip=YESSIR`,
to build quick using 2.11.0-M2 (skipping locker, using starr instead).

Reduced copy/pasting to the best of my antabilities.
The next person to duplicate anything without written
permission will be sentenced to a week in xmhell.
While I was at it, made sure that layering is respected.
The quick phase exclusively uses the locker compiler for building.
The jar task will fail when trying to create an empty jar.
Replaced the crazy if/unless/depends constructs by if/then/else.
Version suffix computation should now be comprehensible.
I threw in some validation to make sure the various suffixes are consistent.
Also, no more init/pre-foo tasks unless absolutely necessary.
Introduced a couple of macros to capture the essence of staged compilation.
Notes:
- remove lib.extra, standardize on aux.libs
- collapse *.javac.path and *.build.path
- rename starr.classpath to starr.compiler.path
- only repl needs jline, locker.compiler.path = locker.comp.build.path + forkjoin
- more uniform build.paths (compiler = reflect + library)
- uniformity means slightly bigger classpaths
(e.g. forkjoin is only used in library, but inherited by compiler)
- pruned: some spurious dependencies removed
- compilerpathref = compiler build path
- silence test.osgi, by hook or by crook
- centralized clean tasks
- reduce duplication in property usage
- fix pack.xml to pack scaladoc/partest instead of scaladoc/scala-partest

SI-7235 is caused by a long-standing todo in typedRefinement, which leads
to originals of compound type trees swallowing their stats.
I'm not sure how exactly to fix SI-7235, but what I am sure about is that
we shouldn't silently discard stats during reification. This patch
introduces a new implementation restrictions, which now reports that
reify of compound type trees with non-empty stats isn't going to work.

TypeVars, being mutable creatures, mustn't have structural
equality/hashing, otherwise TypeRefs that differ only by
having distinct TypeVars as components get wrongly uniqued
together.
The reported bug showed the disaterous consequences: constraints
from the `C?[Int]` in the return type applied to the `?C[?A]` in
the parameter list.
This commit overrides `equals` and `hashCode` in `TypeVar`
to use reference equality. An alternative fix would be to drop
the `case`-ness of the class, as was the case before 0cde930b
when this regressed.

Don't focus positions assigned to the TypeTree of a parent of a Template
when the parent exists in the source. A focused position (instance
of `OffsetPosition`) makes it invisible to the presentation compiler
when it looks for the innermost enclosing tree of a given position
(breaking hyperlinking, for example).

SI-7214 outer check based on dealiased pattern type.

A Typed Pattern (_: T) is more than `.isInstanceOf`: if `T` is a
path dependent type, the scrutinee's $outer reference is also
compared against the prefix of `T`.
The code that synthesises this is split into two places.
`needsOuterCheck` determines whether to add this check, based on
the type `T`, and the type of the scrutinee. If it gives the
go-ahead, `treeCondStrategy.outerCheck` synthesizes the check.
The new test case demonstrates the problems caused by the failure
to dealias in `needsOuterCheck`: it could either wrongly lead to
synthesis of an outer test (which would crash), or wrongly omit
the outer test (meaning overly liberal matching.)
A simple `dealias` remedies this. `dealiasWiden` is *not*
appropriate here; we need to keep hold of singleton types.
I'll also note that there is already a little slack between these
methods, as commented:
> ExplicitOuter replaces `Select(q, outerSym) OBJ_EQ expectedPrefix`
> by `Select(q, > outerAccessor(outerSym.owner)) OBJ_EQ expectedPrefix`
> if there's an outer accessor, otherwise the condition becomes `true`
> TODO: can we improve needsOuterTest so there's always an outerAccessor?
So this is probably a fragile area that warrants a careful review
with a view to design improvements.

We want 2.10.1 to be a drop-in replacement for 2.10.0,
so we can't start warning where we weren't warning in 2.10.0.
See SI-5954 (#1882, #2079) for when it was an implementation restriction,
which was then weakened to a warning. It's now hidden behind -Ydebug.

This avoids spurious unreachable warnings on code
that the user didn't write.
The parser desugars for-comprehensions such as:
for (A(a) <- List(new A)) yield a
To:
List(new A()).withFilter(((check$ifrefutable$2) =>
check$ifrefutable$2: @scala.unhecked match {
case A((a @ _)) => true
case _ => false
})
)
But, if `A.unapply` returns `Some[_]`, the last case is dead code.
(Matching against a regular case class *would* fall through in
the caes of a null scrutinee.)
In SI-6902, we enabled unreachability warnings, even if the
scrutinee was annotated as @unchecked. That was consistent
with the 2.9.2 behaviour, it was only disabled temporarily
(actually, accidentally) in 2.10.0. But, the old pattern matcher
didn't warn about this code.
This commit makes the pattern matcher recognise the special
scrutinee based on its name and disables both exhaustivity
*and* unreachability analysis.
To do so, the we generalize the boolean flag `unchecked` to
the class `Suppression`.

The kind-polymorphic nature of Nothing and Any in
concert with type argument inference could lead to
types like `T[T]` (where `type T=Any`).
Compensatory action is taken later on to recover;
see the usages of `TypeRef#typeParamsMatchArgs`.
But this these types have a nasty property, they
can dealias to themselves. Callers recursing through
types who fail to account for this hit an infinite
recursion, as was reported in SI-7126.
This commit simply dealiases `T` when registering
the type bound in `unifySimple`.
We should try to weed out additional sources of
these types.
