ARM: restrict register class for WIN__DBZCHK
WIN__DBZCHK will insert a CBZ instruction into the stream. This instruction
reserves 3 bits for the condition register (rn). As such, we must ensure that
we restrict the register to a low register. Use the tGPR class instead of GPR
to ensure that this is properly constrained. In debug builds, we would attempt
to use lr as a condition register which would silently get truncated with no
hint that the register selection was incorrect.
