This adds some extra RUN lines to existing test files, to check that
things that worked in previous architecture versions haven't
accidentally stopped working in 8.1-M. Also we add some new tests: a
test of scalar floating point instructions that could be easily
confused with the similar-looking vector ones at assembly time, a test
of basic load/store/move access to the FP registers (which has to work
even in integer-only MVE); and one final check of the really obvious
case where turning off MVE should make sure MVE instructions really
are rejected.

The MVE extension in Arm v8.1-M permits the use of some move, load and
store isntructions which access the FP registers, even if there's no
actual FP support in the processor (in particular, if you have the
integer-only version of MVE).
Therefore, we need separate subtarget features to condition those
instructions on, which are implied by both FP and MVE but are not part
of either.
Patch mostly by Simon Tatham.
