efc0d24037 fsel can take a different FP type for the comparison and for the result. As such
split the FSEL family into 4 things instead of just two.

b66cf00015 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.

37fdc6dbf9 Add some very paranoid checking for operand/result reg class matchup
For instructions that define multiple results, use the right regclass
to define the result, not always the rc of result #0

50411b1026 Modify the ppc backend to use two register classes for FP: F8RC and F4RC.
These are used to represent float and double values, and the two regclasses
contain the same physical registers.

9c069d09a5 Annotate nodes with their addresses if a graph requests it.
This is Jim's feature implemented so that graphs could 'opt-in' and get
this behavior.  This is currently used by selection dags.
