Summary: Previously, it returned the GPR16MMRegClass for all instructions which was incorrect for instructions like lwsp/lwgp and unnecesarily restricted the permitted registers for instructions like lw32. This fixes quite a few of the -verify-machineinstrs errors reported in PR27458. I've only added -verify-machineinstrs to one test in this change since I understand there is a plan to enable the verifier by default.
