[Bug target/19326] New: gcc.c-torture/execute/simd-6.c fails on x86-64

["aj at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

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.
