[Hexagon] Fix dependence check in the packetizer An incorrect check in the packetizer lead to an attempt to convert an unconditional branch to a .new (conditional) form. llvm-svn: 304442

# RUN: llc -march=hexagon -start-after if-converter %s -o - | FileCheck %s
# CHECK: p0 = r0
# CHECK-NEXT: jumpr r31
# Make sure that the packetizer does not attempt to newify the J2_jumpr
# only because of the def-use of p0.

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
