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

# bb.2 has no successors, presumably because __stack_chk_fail doesn't return,
# so there should be no edge from bb.2 to bb.3.
# Nevertheless, IfConversion treats bb.1, bb.2, bb.3 as a triangle and
# inserts a predicated copy of bb.2 in bb.1.
# This caused r302876 to die with a failed assertion.
