Don't enable -fprefetch-loop-arrays for TARGET_SOFTWARE_PREFETCHING_BENEFICIAL if -Os.
Testing an x86_64 toolchain configured for a processor with
TARGET_SOFTWARE_PREFETCHING_BENEFICIAL produces failures

FAIL: g++.dg/pr60518.C -std=gnu++11 (test for excess errors)

Given that lack of support, it seems appropriate for the back end not
to enable this option in the -Os case; this patch implements that.

for a cross to x86_64-linux-gnu --with-arch=btver2, where those test
failures duly disappear.
