[PATCH] s390: Add -munroll-only-small-loops.

Hi, inspired by Power we also introduce -munroll-only-small-loops. This implies activating -funroll-loops and -munroll-only-small-loops at -O2 and above. Bootstrapped and regtested. This introduces one regression in gcc.dg/sms-compare-debug-1.c but currently dumps for sms are broken as well.
