gcc.target/i386/apx-interrupt-1.c and two more tests FAIL on Solaris/x86
with the native assembler. Like Darwin as, it doesn't support cfi
directives. Instead of adding more and more targets in every affected
test, this patch introduces a cfi effective-target keyword to check for
the prerequisite.
Tested on i386-pc-solaris2.11 (as and gas), x86_64-pc-linux-gnu, and
x86_64-apple-darwin23.1.0.
Any comments on the CFI detection in target-supports.exp? Otherwise,
I'll commit the patch as is.
The tests still FAIL on Solaris/x86 and FreeBSD/x86_64 with gas due to
their -fno-omit-frame-pointer default; this will be addressed
separately.
Thanks.
Raine

Given that nobody found fault with the CFI detection, I've rebased the
patch to account for the -fomit-frame-pointer changes, retested and
committed it to trunk.

This has been handled now.
