re PR target/59003 (profiledbootstrap miscompiles gcc during stagefeedback --with-tune=amdfam10)

PR target/59003
* config/i386/i386.c (expand_small_movmem_or_setmem): If mode is
smaller than size, perform several stores or loads and stores
at dst + count - size to store or copy all of size bytes, rather
than just last modesize bytes.

* gcc.dg/tree-prof/pr59003.c: New test.
