Implement the forms of the MVE VLDR and VSTR insns which perform
non-widening loads of bytes, halfwords or words from memory into
vector elements of the same width (encodings T5, T6, T7).
(At the moment we know for MVE and M-profile in general that
vfp_access_check() can never return false, but we include the
conventional return-true-on-failure check for consistency
with non-M-profile translation code.)

Changes v2->v3: pass MSIZE to specify memory size,
and advance addr by that rather than by ESIZE;
advance addr always, not only when predication passes.
