a41fc77ae4 To go along with sabre's improved InstCombining, improve recognition of
integers that we can use as immediate values in instructions.

Example from yacr2:
-       lis r10, -1
-       ori r10, r10, 65535
-       add r28, r28, r10
+       addi r28, r28, -1
        addi r7, r7, 1
        addi r9, r9, 1

645495d2e6 Fix the last of the major PPC GEP folding deficiencies. This will allow
the ISel to use indexed and non-zero immediate offsets for GEPs that have
more than one use.  This is common for instruction sequences such as a load
followed by a modify and store to the same address.

3e0b51ab3b * Change PPC32AsmPrinter => PowerPCAsmPrinter since it is now shared between

a96c4af7f1 Back out branchless SetCC code. While it helped a lot in some cases, it

dig it up again.
