Add a TARGET_GEN_MEMSET_VALUE hook

builtin_memset_gen_str returns a register used for memset, which only
supports integer registers. But a target may use vector registers in
memmset. This patch adds a TARGET_GEN_MEMSET_VALUE hook to duplicate
QImode value to mode derived from STORE_MAX_PIECES, which can be used
with vector instructions. The default hook is the same as the original
builtin_memset_gen_str. A target can override it to support vector
instructions for STORE_MAX_PIECES.
