inline: do not einline when no_profile_instrument_function is different
PR gcov-profile/80223
gcc/ChangeLog:
* ipa-inline.c (can_inline_edge_p): Similarly to sanitizer
options, do not inline when no_profile_instrument_function
attributes are different in early inliner. It's fine to inline
it after PGO instrumentation.
gcc/testsuite/ChangeLog:
* gcc.dg/no_profile_instrument_function-attr-2.c: New test.
