It is discovered that `test-suite` in case of microMIPS is failing after committing this patch into mainline. test.log contained error messages like:

  /tmp/ConditionalExpr-b127f7.s: Assembler messages:
  /tmp/ConditionalExpr-b127f7.s:487: Error: invalid operands `lw16 $4,0($1)'
  /tmp/ConditionalExpr-b127f7.s:489: Error: invalid operands `sw16 $4,0($1)'

I found out that i forgot to change MipsRegisterInfo::getPointerRegClass() in order to support GPRMM16 and GPRMM16_64 register classes. After this fix, manual execution of `test-suite` is passing. So please, review this change once again.
