d4c615be8c Followup on Proposal to move MIR physical register namespace to '$' sigil. 
Discussed here:

http://lists.llvm.org/pipermail/llvm-dev/2018-January/120320.html

In preparation for adding support for named vregs we are changing the sigil for
physical registers in MIR to '$' from '%'. This will prevent name clashes of
named physical register with named vregs.

4a9ea2a58e [AMDGPU] Turn s_and_saveexec_b64 into s_and_b64 if result is unused 
With SI_END_CF elimination for some nested control flow we can now
eliminate saved exec register completely by turning a saveexec version
of instruction into just a logical instruction.
