CPol and CPol_GLC1 operand classes have identical predicates, which means AsmParser cannot differentiate between the RTN and non-RTN variants of the instructions. When it currently selects the wrong instruction, a hack in cvtSMEMAtomic() corrects the op-code. Using the new predicated-value operands makes this hack and the whole conversion function not needed. Other uses of CPol_GLC1 operands are to be addressed separately. Resolves about half of the remaining ~1000 pairs of ambiguous instructions.
