Start pulling cases out of PPC32DAGToDAGISel::Select. With GCC 4, this function

another solution to the fsel issue. Instead of having 4 variants, just force

Minor tweak to the branch selector. When emitting a two-way branch, and if
...
we're in a single-mbb loop, make sure to emit the backwards branch as the
conditional branch instead of the uncond branch. For example, emit this:
LBBl29_z__44:
stw r9, 0(r15)
stw r9, 4(r15)
stw r9, 8(r15)
stw r9, 12(r15)
addi r15, r15, 16
addi r8, r8, 1
cmpw cr0, r8, r28
ble cr0, LBBl29_z__44
b LBBl29_z__48 *** NOT PART OF LOOP
Instead of:
LBBl29_z__44:
stw r9, 0(r15)
stw r9, 4(r15)
stw r9, 8(r15)
stw r9, 12(r15)
addi r15, r15, 16
addi r8, r8, 1
cmpw cr0, r8, r28
bgt cr0, LBBl29_z__48 *** PART OF LOOP!
b LBBl29_z__44
The former sequence has one fewer dispatch group for the loop body.
