[PATCH] Shut up bogus clang warning on omp-low.c (PR middle-end/89137)

[Jakub Jelinek]

Hi!

In an if (code == OMP_FOR || code == OMP_SECTIONS) guarded block c will be
always initialized, yet clang warns anyway.

Changed thusly, bootstrapped/regtested on x86_64-linux and i686-linux,
committed to trunk.
