[ARM GlobalISel] Select load/store for Thumb2

Unfortunately we can't use TableGen for this because it doesn't yet
support predicates on the source pattern root. Therefore, add a bit of
handwritten code to the instruction selector to handle the most basic
cases.

Also mark them as legal and extract their legalizer test cases to a new
test file.
