This is used when fastmem isn't available. Instead of always falling
back to the C++ code in MMU.cpp, the JIT translates addresses on its
own by looking them up in a table that Dolphin constructs. This is
slower than fastmem, but faster than the old non-fastmem code.
This is primarily useful for iOS, since that's the only major platform
nowadays where you can't reliably get fastmem. I think it would make
sense to merge this feature to master despite this, since there's
nothing actually iOS-specific about the feature. It would be of use
for me when I have to disable fastmem to stop Android Studio from
constantly breaking on segfaults, for instance.

Without this, debug builds of Dolphin fail to launch. The OS tries
to locate org.dolphinemu.dolphinemu.debug.DolphinApplication
but fails to find it because its actual name is
org.dolphinemu.dolphinemu.DolphinApplication.

It was removed for non-android in 56239d1ae139998a7cde17ff02f0526ffb17f5ef, and android already uses a separate thread, so presumably this isn't needed anymore.
This hack was added in 8f0cbefbe57762de92284ef151e984f52ec8d7e6, and the part of it in SI_DeviceGCAdapter is present on Android already, so I don't see any reason why this part doesn't apply to Android.
This is mostly a brainless merge, #ifdef-ing anything that doesn't match between the two while preserving common logic. I didn't rename any variables (although similar ones do exist), but I did change one log that was ERROR on android and NOTICE elsewhere to just always be NOTICE. Further merging will follow.
Instead, saturate in OpReadRegister, as all uses of OpReadRegisterAndSaturate called OpReadRegister for other registers (and there isn't anything that writes to $ac0.m or $ac1.m without saturation).
The current code expects new mail almost immediately after the last map was sent for it to be saved properly. However, I have a test program that ends up looping for 32768 iterations before it sends more mail; this resulted in an incomplete result dump. I've changed it to wait a frame between checking for mail, which solves that issue. This does slow down dumping, but the end speed matches the speed at which the UI updates the registers so this isn't a big deal (the UI waits a frame between mail normally). (Theoretically, it could take even longer for dumping to finish, so this is not a perfect solution. However, for tests that take that long to run, it would be better to save the existing results instead of re-running the test and saving that; that'd be something to do with later improvements.)
