We sometimes want to analyze codegen in multiple regions, it'd be useful if we
could nest and overlap region markers to support this:


testloop:
# LLVM-MCA-BEGIN outer
  leal 42(%rdi), %eax
# LLVM-MCA-BEGIN inner
  imull %esi, %eax
# LLVM-MCA-END inner
  leal 42(%rdi), %eax
# LLVM-MCA-END outer
  imull %esi, %eax



testloop:
# LLVM-MCA-BEGIN upper
  leal 42(%rdi), %eax
# LLVM-MCA-BEGIN lower
  imull %esi, %eax
# LLVM-MCA-END upper
  leal 42(%rdi), %eax
# LLVM-MCA-END lower
  imull %esi, %eax
