Hal Finkel 184f8f7c10 [PowerPC] Enable printing instructions using aliases 
TableGen had been nicely generating code to print a number of instructions using
shorter aliases (and PowerPC has plenty of short mnemonics), but we were not
calling it. For some of the aliases we support in the parser, TableGen can't
infer the "inverse" alias relationship, so there is still more to do.

Thus, after some hours of updating test cases...

; registers and with -fast-isel-abort=1 turned on the test case will then fail.
; When fastisel better supports VSX fix up this test case.
