FEAT_MTE_STORE_ONLY introduces control if Load instructions are Tag
Unchecked. Let's add support for that feature, yet (as usual) we need
to take extra care for CAS and friends:
RMNHCZ If FEAT_MTE_STORE_ONLY is implemented, for a Tag Checked
Compare and swap instruction, if the compare fails, it is
CONSTRAINED UNPREDICTABLE whether the Tag Check operation is
performed.
