[AMDGPU] Prevent post-RA scheduler from breaking memory clauses The pre-RA scheduler does load/store clustering, but post-RA scheduler undoes it. Add mutation to prevent it. Differential Revision: https://reviews.llvm.org/D38014 llvm-svn: 313670

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. llvm-svn: 323922
