3da59db637 For PR950:
The long awaited CAST patch. This introduces 12 new instructions into LLVM
to replace the cast instruction. Corresponding changes throughout LLVM are
provided. This passes llvm-test, llvm/test, and SPEC CPUINT2000 with the
exception of 175.vpr which fails only on a slight floating point output
difference.

fef02427cd completely revert patrick's enhancement to bugpoint. Though it makes bugpoint
speed up, it sometimes makes it crash on complex bc files, which isn't very nice.


With this, bugpoint can reduce the 176.gcc failure.

b83eb6447b For PR950:
This patch implements the first increment for the Signless Types feature.
All changes pertain to removing the ConstantSInt and ConstantUInt classes
in favor of just using ConstantInt.

e47863e212 This commit improves bugpoints speed. On my G4 this changed caused kimwitu++ to run through bugpoint in 1091.15 seconds (user + system time). The time it took to run this on my G4 before I made these changes is 1420.82 seconds (user + system time). This is a speedup of about 5.5 minutes.
This is faster because SplitFunctionsOutOfModule no longer calls Clone Module and then removes the functions it doesnt want from the module returned. Instead it creates a module and copies over the specified functions, making changes to the new and old module where neccessary. This reduces the memory demand.

9b5b1905db Fix a bugpoint crash that JeffC noticed, looking like this:
*** Attempting to perform final cleanups: Final cleanups failed.  Sorry. :(  Ple
ase report a bug!

<llc>llc.exe: bytecode didn't read correctly.
llc.exe: bytecode didn't read correctly.
<crash>
Assertion failed: M && "You can't write a null module!!", file c:\llvm\lib\bytec
ode\writer\writer.cpp, line 1094


The fact that llc bombed (in this case) is ok, but bugpoint shouldn't crash after this.

from ModulePass.  Instead of implementing Pass::run, then should implement
ModulePass::runOnModule.

5e783ab0b5 Implement basic block extraction for the miscompilation debugger. This still needs
two things: the FIXME in ExtractBlocks needs to be implemented, and the basic block
extractor itself needs to have enough bugs fixed for this to be more or less
useful.

Until the time that this is generally useful, it is hidden behind the new bugpoint
-enable-block-extraction option.  I hope to get the FIXME done tonight.

Also of note, this patch adds a -extract-bbs option to bugpoint which can be used
to debug the block extractor.  (hint hint Misha :)

a1cf1c8c87 After reducing a miscompiled program down to the functions which are being
miscompiled, try to use the loop extractor to reduce the program down to a
loop nest that is being miscompiled.  In practice, the loop extractor appears
to have too many bugs for this to be useful, but hopefully they will be fixed
soon...

efdc0b5057 Refactor and clean up a bunch more code. No major functionality changes.
* Make several methods of bugdriver global functions (ParseInputFile, PrintFunctionList)
 * Make PrintFunctionList truncate the output after 10 entries, like the crash debugger
   did.  This allows code sharing.
 * Add a couple of methods to BugDriver that allows us to eliminate some friends
 * Improve comments in ExtractFunction.cpp
 * Make classes that used to be friends up bugdriver now live in anon namespaces
 * Rip a bunch of functionality in the miscompilation tester into a new
   TestMergedProgram function for future code sharing.
 * Fix a bug in the miscompilation tester induced in my last checkin

fcb6ec0c7e I hate it when bugpoint is all ready to give me a bytecode file, then crashes
in final cleanups.  Then you had to run the whole mess again with
-disable-final-cleanups.

This makes bugpoint run the cleanups in a protected environment so that if
they crash, bugpoint itself doesn't crash.  This makes things much happier,
implements a FIXME, and gets rid of YABPO (yet another bugpoint option).
