tcg: Disambiguate qemu_ld32u with 32-bit and 64-bit outputs.
Some targets (e.g. Alpha and MIPS64) need to keep 32-bit operandssign-extended in 64-bit registers (regardless of the "real" signof the operand). For that, we need to be able to distinguishbetween a 32-bit load with a 32-bit result and a 32-bit load with...
