1.+(2) - what is it? Is it 3 or 3.0? Come scala 2.11 you won't
have to not know (or even not know there's something you don't know.)
1.+(2) will then be safely considered equivalent to 1 + 2, because
any dot not followed by a digit is not part of a number.
Primarily, that's these forms: 3.f 3.d 3.
If you prefer an error to a warning, use -Xfuture.

Tweaked implementation of invalidClassName method
to exclude *$class clasess from the set of invalid
names. It's not exactly clear what was the intent
of this method in first place so I'm not sure if
it's the best way to fix SI-5176. Added test-case
that covers this issue.

Enabled fancy type inference if opt.virtPatMat is true so one need
not enable -Xexperimental to use El Virto (since I keep wasting time on
edge cases arising from unrelated -Xexperimental-enabled features.)

I should know better than to behave as if usable inferences can
be drawn from a comment like "SYNTHETIC because of DEVIRTUALIZE".
Maybe it was even true when it was written, but no more.

the long-term goal is to separate:
- analyzing patterns and turning them into extractors that are flatMap'ed and orElse'ed,
where the structure is expressed in a small intermediate language that
preserves more pattern matching-specific meaning than trees
- more advanced analyses on the intermediate representation
- code generation (patmat IR -> Scala AST) -- this should be trivial

Created MsilFile as a wrapper around MSILType so we can use AbstractFile
everywhere. This initial attempt is fairly ham-fisted, since I'm not
sure exactly how things are used on the msil side; but it is imposing
undue complication on the loaders. Review by magarcia.

Some philistine who thinks "binary compatibility" is

wraps the call to a bridged synthetic unapply(Seq) in a defensive if-test:
if (x.isInstanceOf[expectedType]) real.unapply(x.asInstanceOf[expectedType]) else None
NOTE: the test is WRONG, but it has to be due to #1697/#2337 -- once those are fixed, this one should generate the expected output

This commit and the two subsequent commits were contributed by:
Todd Vierling <tv@duh.org>.
I combined some commits and mangled his commit messages, but all the
credit is his. This pursues the same approach to classfile reduction
seen in r19989 when AbstractFunctionN was introduced, but applies it to
the collections. Thanks to -Xlint it's easy to verify that the private
types don't escape.
Design considerations as articulated by Todd:
* Don't necessarily create concrete types for _everything_. Where a
subtrait only provides a few additional methods, don't bother; instead,
use the supertrait's concrete class and retain the "with". For example,
"extends AbstractSeq[A] with LinearSeq[A]".
* Examine all classes with .class file size greater than 10k. Named
classes and class names ending in $$anon$<num> are candidates for
analysis.
* If a return type is currently inferred where an anon subclass would be
returned, make the return type explicit. Don't allow the library-private
abstract classes to leak into the public namespace [and scaladoc].

Moved all the eagerly evaluated bits to the top of the file so
I can see them all at once. Let a dozen vals unroll up front so
initialization is more predictable. No review.

As near as I can tell, -Xcheckinit was failing because a var was read
too early as null rather than waiting for it to be set to its initial
value, null. I guess that's a defensible warning, since one might change
it away from null. Organized the vars in that file better. No review.

Hardened the repl against a bunch of erroneous conditions.
Added a :reset command which causes the repl to forget everything
you have told it. Added classloader tracing when repl tracing is
enabled. :reset is not that useful in its current form but
it's the precursor to something more interesting. No review.

Exception handling beset by entropy. Restored some order. The output of
the test may not be stable across platforms, in which case I'll take the
usual step of reverting it, thereby achieving victory over failure by
testing nothing instead of testing something. No review.

With this change, one can use the reflective compiler with the
scala libs on the boot classpath (the default) or not (with -nobootcp)
and it will work either way. Maybe it will work in sbt now too, but
I haven't tried it. Since I bet you will try it, review by grek.
