[mips] Check the register class before replacing materializations of zero with $zero in microMIPS.
Summary:
The microMIPS register class GPRMM16 does not contain the $zero register.
However, MipsSEDAGToDAGISel::replaceUsesWithZeroReg() would replace uses
of the $dst register:
[d]addiu, $dst, $zero, 0
with the $zero register, without checking for membership in the register
class of the target machine operand.
