184f8f7c10 [PowerPC] Enable printing instructions using aliases
TableGen had been nicely generating code to print a number of instructions using

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...

hwsync is only required for seq_cst fences, acquire and release one can use
the cheaper lwsync.
