    testsuite: fix ASAN errors
    
    The tests failed on my machine as they contain out-of-bounds
    access.
    
    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.
