6830bee9b4 Remove the Backwards operation. Resolving now works at the time when a 
property is added by running through the list of uses of the value and
adding resolved properties to the property set.

This will allow (after llvm-gcc linkage fix) more dummy tests using
libstdc++ to pass on mingw :)

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.

50b3810d9a 3 Changes: 
1. Better document what is going on here.
2. Only hack on one branch per iteration, making the results less conservative.
3. Handle the problematic case by marking edges executable instead of by
   playing with value lattice states.  This is far less pessimistic, and fixes
   SCCP/ipsccp-gvar.ll.

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.

-       jmp LBB26_227   #bb7119

 LBB26_208:     #cond_true6020
        movl $l31_str14, 4(%esp)

        testl %eax, %eax
-       jne LBB26_704   #cond_true13042
-       jmp LBB26_713   #bb13151
+       je LBB26_713    #bb13151
 LBB26_704:     #cond_true13042
        movl $_str52, 4(%esp)

        cmpl 76(%ecx), %eax
-       jge LBB26_1628  #cond_false63.i.i
-       jmp LBB26_1769  #_Z8makeGridP13mrSurfaceListidiidd.exit.i
+       jl LBB26_1769   #_Z8makeGridP13mrSurfaceListidiidd.exit.i
 LBB26_1628:    #cond_false63.i.i
        movl $0, 48964(%esp)

d4cb8dc857 Three changes: 
1. Remove a bunch of ifdef'd code.
2. When a block just contains an uncond branch, change all blocks branching
   to it to jump to the destination instead.
3. If branch analysis tells us some edges in the machinecfg are not actually
   possible, remove them.

#2 triggers a suprisingly large number of times.
