Pattern matching on Array types, working for reals.
def f[T](a: Array[T]) = a match {
case x: Array[Int] => x(0)
case x: Array[Double] => 2
// etc.
}
I'd also like to thank "instantiateTypeVar" for displacing the
mechanical spiders and giant squid beings which used to fill my
nightmares. Now that I know true horror, I welcome the squid.

patches for #3887 and #3888, but I determined that I could achieve the
same effect by deleting a bunch of code, so I did. This left only a few
lines in TransMatch, so I eliminated it, which led me to remember that
many places still reference non-existent phase transmatch, so those were
updated. Notes:
* This swaps equality tests on stable identifier patterns. They
have never conformed to the spec (as noted long ago in ticket #785)
which says "The pattern matches any value v such that r == v" whereas
until now the test being performed was v == r.
* An issue was introduced with specialization in that the implementation
of "isTupleType" in Definitions relied upon sym == TupleClass(elems.length).
This test is untrue for specialized tuples, causing mysterious behavior
because only some tuples are specialized. There is now "isTupleTypeOrSubtype"
although it seems likely the former implementation is unnecessary.
The issue is sidestepped if one uses "getProductArgs" to retrieve the element
types because it sifts through the base types for the Product symbol.
Closes #3887 and #3888, review by dmharrah.

Removes a bunch of private functions which are never called. While based
on the nature of "private" one can generally feel pretty good that such
a thing is safe, there is always a chance the author had some future use
in mind. On that note I draw your attention in particular to:
(martin) Typers#stabilizedType: it "sounds" important, but most of it
has been commented out since 2007 and the little stub part is a never
called private.
(iulian) SpecializeTypes#makeTypeArguments: similarly sounds like a
cornerstone of a transformation until one notices it isn't used.
Unused methods are "attractive nuisances" for anyone (like myself) who
has to figure out how the compiler works by studying the compiler, for
reasons which are no doubt obvious. No review except as noted.

Still giddy with the thrill of fixing #266, I vanquish another pattern
matcher bug from the dawn of time. If you've always wanted to write code
like this:
class Bob[K[_]] {
def foo(other: Any) = other match {
case x: (Bob[X] forSome { type X[_] }) =>
}
}
Now is your chance. Closes #1427, review by moors. (Is there a better
way to "shake off" the pattern existential?)

While trying to come to an understanding with #3869 I had one of those
"what are we doing" moments regarding the reams of output generated
under -Ydebug. We have all these places where extra
info is logged under -Ydebug -- like "if (debug) log(...)" -- and if
you try for those you are also saddled with all these irrelevant places
which instead say if (debug) Console.println(...).
I changed about every one of them to send it to log() instead. So if you
were enjoying that 600 MB of debugging output when you compile "goodbye
world", you can have it back and then some with -Ylog:all. Until then,
enjoy the calm, quiet competence of the new -Ydebug.
Also herein: raised default ANT_OPTS permgen because I can no longer
build a dist with the former defaults, and gave some synthetics a better
home in StdNames.
No review (but if anyone just can't live without some particular piece
of output every single time -Ydebug is given, I can put it back.)

Modified typekinds to offer a more general lub when it encounters
interfaces so it does not end up in a disagreement with the jvm.
References #3872, but modifying the compiler lubs is not yet done.

situations where a mutable var will later be lifted. As a point of
interest, this bug reveals itself fairly clearly if you use a build
since r23112 and run the checker thusly:
scalac -d /tmp -Ycheck-debug -Ycheck:icode -Xprint:icode
test/files/run/bug3855.scala
It dies with the following explanation:
Output changed for Block 3 [S: 2] [P: 1, 4]
Exception in thread "main" scala.tools.nsc.backend.icode.CheckerException:
Incompatible stacks: TypeStack() and TypeStack(2 elems) {
REFERENCE(class IntRef)
REFERENCE(class IntRef)
} in Test.main at entry to block: 2
And indeed that was the source of the reported verifyerror.

A little reorganization of some pattern matcher logic. I must have a
short memory to even consider touching it, but maybe I'm still infused
with the mario invulnerability star one receives after some time spent
consulting with martin. No review.

Refined crash avoidance related to self type tests in anonymous classes
as introduced for #576. Now it really only excludes anonymous classes.
Suddenly, this works:
override def equals(other: Any) = other match {
case _: this.type => true
case _ => false
}
Who will be the first to roll out some reference equality in the
this.type style? No review.

build/pack/bin/scalac -d /tmp -Ycheck-debug -Ycheck:all \
src/compiler/scala/tools/nsc/Global.scala
That blows up in constructors as most files do, so also try it with
-Ycheck:icode to see the pretty icode output (for a little while anyway,
after which it will again blow up.)
Our work has only just begun! See test/checker-tests/fail*.scala for
11 examples of places where the checker cries foul. Many of them are
telling us about real issues and we should listen, but I will need help
to figure out which are legitimate and which should be eliminated by
altering the checkers.
This patch also hacks on some territory the checkers drew me into,
especially TypeKinds, where I figured anything which had been commented
out since 2005 was fair game.
(Optional) review by dragos. (The one place I know I could use a look is
in Checkers.scala, because I had to relax some checks and add at least
one newer opcode.)

Painstaking elimination of redundant array creation code, also
eliminating the lingering usage of "wrapArray" which it has long been
noted can go away after next newstarr and now perhaps it really can. A
very careful patch so I'll say no review, but it's a bit of a sensitive
area so feel free to go reviewing anyway.
