convert PPC::BCC to use the 'pred' operand instead of separate predicate
...
value and CR reg #. This requires swapping the order of these everywhere
that touches BCC and requires us to write custom matching logic for

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.
