Since *mov<mode>_internal and <avx512>_(load|store)<mode>_mask patterns
can handle unaligned load and store, we can remove UNSPEC_LOADU and
UNSPEC_STOREU.  We use function prototypes with pointer to scalar for
unaligned load/store builtin functions so that memory passed to
*mov<mode>_internal is unaligned.
