e6ba8a819c 1. Clean up code due to changes in SwitchTo*Section(2)
2. Added partial debug support for mingw\cygwin targets (the same as
   Linux\ELF). Please note, that currently mingw\cygwin uses 'stabs' format
   for storing debug info by default, thus many (runtime) libraries has
   this information included. These formats shouldn't be mixed in one binary
   ('stabs' & 'DWARF'), otherwise binutils tools will be confused.

9867bf5eaf Unbreaking static ctors patch.
Defaulting second arguments of SwitchTo*Section, this should make things
somehow clearer.

ed0b1b4b24 fix miscompilation of llvm.isunordered, where we branched on the opposite
condition.  This fixes miscompilation of Olden/bh and many others.

db06ed9156 Add debug support for X86/ELF targets (Linux). This allows llvm-gcc4
generated object modules to be debugged with gdb. Hopefully this helps
pre-release debugging.

6fe4efd730 the code in question is now:
cmpw cr0, r7, r3
        ble cr0, LBB1_5 ;bb25
LBB1_8: ;bb17
        cmpw cr0, r8, r5
        bgt cr0, LBB1_2 ;bb

which is just as good as crnand.

6833ffe8b8 For PR950:
Make necessary changes to support DIV -> [SUF]Div. This changes llvm to
have three division instructions: signed, unsigned, floating point. The
bytecode and assembler are bacwards compatible, however.

1abe8bd233 During vector shuffle lowering, we sometimes commute a vector shuffle to try
to match MOVL (movss, movsd, etc.). Don't forget to commute it back and try
unpck* and shufp* if that doesn't pan out.

65b4f5b2dd Don't generate a prototype for _setjmp. At least on Linux, this function
has a different prototype than the one #included from <setjmp.h>. This
patch fixes siod and a number of other test cases on Linux that were
failing the CBE because of this _setjmp issue.

a9adb1e558 Implement support for branch reversal, fix a bug in branch analysis.
This provides stuff like:

        cmpw cr0, r15, r29
        mr r14, r15
-       bge cr0, LBB3_111       ;bb656
-       b LBB3_90       ;bb501
+       blt cr0, LBB3_90        ;bb501
 LBB3_111:      ;bb656
        lwz r18, 68(r1)

which is particularly good for dispatch group formation.
