[cfi-verify tests]: Skip two x86-only tests if x86 is not enabled

nico · nico · commit e6e69f3bd4b8 · 2023-09-11T14:31:39.000-07:00
With this, check-llvm passes on an arm mac if x86 isn't in
LLVM_TARGETS_TO_BUILD.

This pattern to skip the tests if x86 isn't enabled is used
in every other test in this file.
