The 'trick' for then len_load/len_store patterns is
to allow a QImode/byte-only length rather than elements.

I am not sure why you mention 'len' in bytes.
Thanks.

Hi, Richi and Richard.
This patch is adding LEN_MASK_{GATHER_LOAD,SCATTER_STORE} to allow targets
handle flow control by mask and loop control by length on gather/scatter memory
operations. Consider this following case:
#include
void
f (uint8_t *restrict a,
uint8_t *rest
