On x86-32 the word PUSH (50+rd) and POP (58+rd) instructions assume only 32-bit operands, and on x86-64 they assume only 64-bit operands; in neither case should the absence of an operand size be ambiguous. Those special case were added in f6fb78089060818b4352b540abc44da4f62b95ef and lacking of POP seemed an oversight. This closes https://github.com/llvm/llvm-project/issues/114531.
