    testsuite: Tweak some further tests for modern C changes
    
    On IRC Richi mentioned some FAILs in gcc.target/x86_64 and in pr83126.c.
    
    The following patch fixes the former ones (they need recent binutils to
    be enabled), for pr83126.c because I didn't have graphite configured I've
    just verified that the test compiles (didn't without the patch) and that
    the gimple dump is identical with one from yesterday's gcc (as it was a
    tree-parloops.cc ICE, I guess identical gimple is all we care about
    and no need to verify it further).

            * gcc.target/x86_64/abi/avx512fp16/m512h/test_passing_m512.c
            (fun_check_passing_m512_8_values, fun_check_passing_m512h_8_values):
            Add missing void return type.
            * gcc.target/x86_64/abi/avx512fp16/m256h/test_passing_m256.c
            (fun_check_passing_m256_8_values, fun_check_passing_m256h_8_values):
            Likewise.
            * gcc.dg/graphite/pr83126.c (ew): Add missing casts to __INTPTR_TYPE__
            and then to int *.
