E.g. for comparing two aligned memory blocks of 15 bytes
we get the following sequence:

GCC has a generic cmpmemsi expansion via the by-pieces framework,
which shows some room for target-specific optimizations.
E.g. for comparing two aligned memory blocks of 15 bytes
we get the following sequence:
my_mem_cmp_aligned_15:
li a4,0
j .L2
.L8:
