[AArch64][GlobalISel] Mark basic binops/memops as legal.

Browse Source 
We currently use and test these, and select most of them. Mark them
as legal even though we don't go through the full ir->asm flow yet.

This doesn't currently have standalone tests, but the verifier will
soon learn to check that the regbankselect/select tests are legal.
