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.

bb7a6d35dd AMDGPU: Move hazard avoidance out of waitcnt pass. 
This is mostly moving VMEM clause breaking into
the hazard recognizer. Also move another hazard
currently handled in the waitcnt pass.

Also stops breaking clauses unless xnack is enabled.
