  -----------
  [X86] Fix cmov-unpredictable MIR tests under expensive checks (#225011)

The machine functions have no body, so the MIR parser sets NoVRegs and
leaves TracksLiveness unset, and the verifier rejects the vregs created
by instruction selection. Declare tracksRegLiveness: true and noVRegs:
false, and add -verify-machineinstrs to the RUN lines.

Fixes https://lab.llvm.org/buildbot/#/builders/187/builds/23887 after
#223469 (commit a3d0da5c2c3cbfc1fc2d569700fd1a6b30c751dc).
