0493113344 Completely rewrite support for the Value::use_* list. Now, all operations on 
this list (except use_size()) are constant time.  Before the killUse method
(used whenever something stopped using a value) was linear time, and thus
very very slow for large programs.

This speeds GCCAS up _substantially_ on large programs: almost 2x for 176.gcc:

176.gcc:     77.07s -> 37.38s
177.mesa:     7.59s ->  5.57s
252.eon:     21.02s -> 19.52s (*)
253.perlbmk: 11.40s -> 13.05s
254.gap:      7.25s -> 7.42s

252.eon would speed up a whole lot more, but optimization time is being
dominated by the inlining pass, which needs to be fixed.

1cad7eb7b0 Substantial cleanups: 
* Add header comment
 * Remove extraneous #includes
 * Move the FileType enum into the GCC class
 * The GCC class is not virtual.
 * Move all of the "constructor" functions into the classes themselves
 * Stop using cl::list as arguments, use std::vector instead (which cl::list
   derives from)
 * Improve comments

d83c90abd7 Extricate the "reverse" support from the depth-first iterator. This is really 
a crappy form of post-order traversal which really does not belong here.  While
we are at it, improve documentation and use a vector instead of a stack.

This improves the post dominator analysis pass by ~5%, and probably also helps
other passes as well.

Dead.

This is a dead header.

It's not pining! It's passed on! This header is no more! It has ceased
to be!  It's expired and gone to meet its maker! It's a stiff! Bereft
of life, it rests in peace! If you hadn't nailed it to the perch it'd
be pushing up the daisies! Its metabolic processes are now history! It's
off the twig! It's kicked the bucket! It's shuffled off its mortal coil,
run down the curtain, and joined the bleeding choir invisibile!! THIS IS
AN EX-HEADER!!

18c3f42894 This checkin basically amounts to a complete rewrite of the type-resolution 
machinery.  This dramatically simplifies how things works, removes irritating
little corner cases, and overall improves speed and reliability.

Highlights of this change are:

1. The exponential algorithm built into the code is now gone.  For example
   the time to disassemble one bytecode file from the mesa benchmark went
   from taking 12.5s to taking 0.16s.
2. The linker bugs should be dramatically reduced.  The one remaining bug
   has to do with constant handling, which I actually introduced in
   "union-find" checkins.
3. The code is much easier to follow, as a result of fewer special cases.
   It's probably also smaller.  yaay.

564dbbf299 There is no reason for Value to be an AbstractTypeUser. This just makes things 
significantly more complete.  Instead, just make DerivedType's AbstractTypeUser's,
and make Value contain a PATypeHolder.  This will also be more efficient in the
future.
