[x86] regenerate checks with update_llc_test_checks.py The dream of a unified check-line auto-generator for all phases of compilation is dead. The llc script has already diverged to be better at its goal, so having 2 scripts that do almost the same thing is just causing confusion. We can rip out the llc ability in update_test_checks.py next and rename it, so it will be clear that we have one script for llc check auto-generation and another for opt. llvm-svn: 305206

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
