[PATCH] D63938: [ARM] Stop using scalar FP instructions in integer-only MVE mode.

Revised patch fixes those two target triples in the tests, and makes the `setAllExpand` calls for f32 and f64 conditional on different things. Also, to make that less cumbersome, I've moved a few re-enabling `setOperationAction` calls into `setAllExpand` itself which otherwise had to be run after every single call.

This version of the patch is intended to apply _before_ D63937 <https://reviews.llvm.org/D63937> rather than after it, because this way round it turned out easier to get the tests to pass in the intermediate state.
