Puyan Lotfi 43e94b15ea 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.
