UserspaceEmulator+LibX86: Add support for 64-bit memory reads and writes (#3584)
This is useful for reading and writing doubles for #3329.
It is also useful for emulating 64-bit binaries.
MemoryOrRegisterReference assumes that 64-bit values are always
memory references since that's enough for fpu support. If we
ever want to emulate 64-bit binaries, that part will need minor
updating.
