Put PREFETCHW back to march=broadwell

PREFETCHW should be both in march=broadwell and march=silvermont.
I move PREFETCHW from march=broadwell to march=silvermont in previous
patch.

gcc/ChangeLog:

* config/i386/i386.h: Add PREFETCHW to march=broadwell.
* doc/invoke.texi: Put PREFETCHW back to relation arch.
