067b86fcab [Sparc] Add more instruction aliases. 
These are mostly from the chart in the SparcV8 spec, section "A.3
Synthetic Instructions".

ccafe05df1 Sparc: support the "set" synthetic instruction. 
This pseudo-instruction expands into 'sethi' and 'or' instructions,
or, just one of them, if the other isn't necessary for a given value.

642098ac59 Sparc: Add alternate aliases for conditional branch instructions.

84a4f73a8e Sparc: disable printing of jmp/call aliases (C++ does it) 
These aliases are handled entirely in C++ and only having TableGen InstAliases
for some of them was confusing LLVM.

This will be tested when the TableGen "should I print this Alias" heuristic is
fixed (very soon).
