s390: Refactor block operation cpymem
Do not perform a libc function call into memcpy in case the size is not
a compile-time constant but bounded and the upper bound is less than or
equal to 256 bytes.
gcc/ChangeLog:
* config/s390/s390-protos.h (s390_expand_cpymem): Change
function signature.
* config/s390/s390.cc (s390_expand_cpymem): For memcpy's less
than or equal to 256 byte do not perform a libc call.
(s390_expand_insv): Adapt new function signature of
s390_expand_cpymem.
* config/s390/s390.md: Change expander into a version which
takes 8 operands.
