[PATCH] Enable frontend-passes.c optimizations even in omp regions etc.

[Jakub Jelinek]

Hi!

optimize_code_node doesn't dive into OpenMP etc. regions.
The following patch fixes it by walking ->block in the default case.

Bootstrapped/regtested on x86_64-linux and i686-linux, ok for trunk?

	* frontend-passes.c (optimize_code_node): Walk block chain by default.
