[Bug target/19427] New: gcc.c-torture/execute/simd-1.c compilation fails for x64_86 and i686 with -msse2

["uros at kss-loka dot si" <gcc-bugzilla at gcc dot gnu dot org>]

This testsuite failure can be reproduced for both x86_64 and i686 with -msse2:

However, on i686 with -msse, the error is different:
