These tests started recently failing:
gcc.c-torture/execute/simd-6.c compilation, -O3 -fomit-frame-pointer
gcc.c-torture/execute/simd-6.c compilation, -O3 -g
gcc.c-torture/execute/simd-6.c compilation, -Os
Note, the tests work fine with -m32 - and also with the other compile options,
just these three fail.
