Routed Stream.+: through cons to avoid some truly pathological

Performance-motivated work: going through SpecializeTypes and
eliminating unnecessary intermediate data structures and multiple
traversals of lists. Also trying to get that code under control: it
dwarfs all other phases in terms of debugging output, and a too-large
percentage of the source is commented out debugging code which looks
past its sell-by date. I realize the patch is a little big for a very
thorough review, but review by dragos, prokopec.

Quoted the windows runner path so "c:\program files (x86)" has some

Reverts r25085 ("Performance tweaks for AbstractFile, no review.") which
apparently is making the IDE refuse to overwrite classfiles. For the
life of me I can't find why there should be any difference. Bowing to
expedience, no review.

When TypeVars were given higher-order abilities, so too should have been
WildcardType, which acts as a plceholder for typevars. Always inflicting
arguments upon it was the cause of #2308. Closes #2308, review by moors.

Fixed an issue with higher kinded type inference on constructors without
any help from adriaan. Provisionally notched belt. Wrapped up as many
tickets as I added characters of code. Closes SI-3343, SI-4018. Review

Deprecated scala.reflect.generic, except for ByteCodecs. After we move
some non-internal things out of scala.reflect.internal we should go back
and improve some deprecation messages (i.e. point somewhere useful.) No

Triumph over various unsolved mysteries of the pattern matcher. More
elimination of redundant ways of doing things. More allowing the typer
to do its typing thing. No review.

Bytecode inspection reveals the pattern matcher leaving a lot more
redundancy in generated trees than is necessary. Added more inteligence
to the process. Review by dragos.

closes #4692: unification in type constructor inference now widens *and*
dealiases when necessary
in 2.8.1 implicit conversion search started with a widened type, so that
combo never came up

Update manually created tree which was calling Predef.error to call
scala.sys.error instead. Created convenience functions in Definitions
for getting package objects akin to those for getting classes and
objects. No review.

More batched performance improvements for io.{ File, Classpath } and
others in the neighborhood. Avoids calling the expensive
getCanonicalPath in favor of getAbsolutePath: I note that because
it has the potential to change compiler behavior at the borders.

Documented what I could figure out about late flags and anti-flags.
Eliminated some indirection in flag usage. Made -Xshow-phases print out
more info about flags if -Ydebug is also given. No review.

Test case for implicits which unwrap typeclasses, something which must
really live on the edge given the multiple ways we've busted it lately.
Also some Array/signature and repl tests. No review.

Views using methods implemented in terms of isEmpty (in particular,
headOption and lastOption) were traversing the collection twice up
to the nonEmpty element, because "if (isEmpty) None else Some(head)"
means calling isEmpty separately from head. I overrode those methods in
TraversableViewLike to avoid the second traversal.
This leaves at least init and tail still in that boat, but they were
getting too involved.
How do I say "review by pool of reviewers", who can help set that up? In
the meantime no review.

Marked some more by-name-argument-using methods with final @inline to
make possible and then encourage their inlining. Knocked almost 300 more
classfiles and 200K off the compiler jar. No review.
