[Uros Bizjak]

Hello!

Attached patch improves pr67609-2.c testcase with the SSE2 runtime
test framework.

2015-11-01  Uros Bizjak  <ubiz...@gmail.com>

    * gcc.target/i386/pr67609-2.c: Include sse2-check.h.
    (sse2_test): Rename from main.  Do not return 0.

Tested on x86_64-linux-gnu {,-m32}  and committed to mainline SVN.

Uros.
