[PATCH] testsuite: Adjust AVX10.2 check_effective_target

[Haochen Jiang]

Hi all,

Since Binutils haven't fully merged all AVX10.2 insts, only testing
one inst/intrin in AVX10.2 is never sufficient for check_effective_target.
Like APX_F, use inline asm to do the target check.

Testes w/ and w/o Binutils with full AVX10.2 support. Ok for trunk?

Thx,
Haochen

gcc/testsuite/ChangeLog:

        PR target/117301
        * lib/target-supports.exp (check_effective_target_avx10_2):
        Use inline asm instead of intrin for check_effective_target.
        (check_effective_target_avx10_2_512): Ditto.
