Add test case for r311511 This also changes the TailDuplicator to be configured explicitely pre/post regalloc rather than relying on the isSSA() flag. This was necessary to have `llc -run-pass` work reliably. llvm-svn: 311520

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
