8c494ab759 Fix a bug in merged condition handling (CodeGen/Generic/2006-10-27-CondFolding.ll).
Add many fewer CFG edges and PHI node entries.  If there is a switch which has
the same block as multiple destinations, only add that block once as a successor/phi
node (in the jumptable case)

4ccf63d8cf 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.

d2f9ee9ea7 Codegen cond&cond with two branches. This compiles (f.e.) PowerPC/and-branch.ll to:

LBB1_3: ;entry
        cmplwi cr0, r3, 0
        bne cr0, LBB1_2 ;UnifiedReturnBlock

instead of:

        ret
LBB1_2: #UnifiedReturnBlock
        addl $12, %esp
        ret

instead of:
