09ef1749f7 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.

d7f07a7f91 Okay, this is a little hack that "scratches an itch" of mine. 
I dislike having to examine the output of "dis" to see what symbols
are in a bytecode file. So, here is a first cut at a "nm" utility for llvm.
Flame away.... :-)

b3414f7cb6 The levelraise pass is a broken old piece of crufty code that should be 
left on the side of the road without a second thought.

It is preventing forward progress, so for now, we will disable it by default.

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

907de53acb Disable the leaf function optimization, which is apparently not legal on 
X86/linux.  :(  The problem is that a signal delivered while the function
is executing could clobber the functions stack.  This is a partial fix
for PR41.

of 3 176.gcc source files (reload1.c, global.c, flow.c)
