[PATCH] testsuite: AMDGCN test for vect-early-break_38.c as well to consistent architecture [PR119286]

[Tamar Christina]

Hi All,

I had missed this one during the AMDGCN test failures.

Like vect-early-break_18.c this test is also scalaring the
loads and thus leading to unexpected vectorization for this
testcase.

Bootstrapped Regtested on aarch64-none-linux-gnu and no issues.

Cross checked the failing case on amdgcn-amdhsa
and all pass now.

Ok for master? and GCC 15?

Thanks,
Tamar

gcc/testsuite/ChangeLog:

        * gcc.dg/vect/vect-early-break_38.c: Force -march=gfx908 for amdgcn.
