[committed][gcc][patch] Require sse for testcase on i686.

[Tamar Christina]

Hi All,

This fixes an ABI warning generated on i686-pc-linux-gnu when using
`vector_size` with no sse enabled explicitly.

Regtested single test on x86_64-pc-linux-gnu with -m32 and no issues.

Committed under the GCC obvious rule.

Thanks,
Tamar
