[PATCH][pushed] testsuite: fix ASAN errors

[Martin Liška]

The tests failed on my machine as they contain out-of-bounds
access.
I'm going to push the fix.

gcc/testsuite/ChangeLog:

        * gcc.target/i386/avx2-psraq-1.c: Use ARRAY_SIZE.
        * gcc.target/i386/m128-check.h: Move it to the top-level
        context.
        * gcc.target/i386/sse2-psraq-1.c: Use ARRAY_SIZE.
        * gcc.target/i386/sse4_2-check.h: Include the header with
        ARRAY_SIZE definition.
