Actually

Actually, this is pretty pervasive in the armv7 macroassembler; will look and see what, if any patch, we should have to address.

In principle, AIUI, not invalidating the cached value for the data/address temps when clobbering them could misbehave badly, but in practice I imagine it's difficult/near-impossible to trigger.
