[x86] regenerate checks

Browse Source 
utils/update_test_checks.py was improved with:
http://reviews.llvm.org/rL265414
to include the first line of the function (expected to be
a comment line). This ensures that nothing bad has happened
before the first actual line of checked asm. It also matches
the existing behavior of the old script.
