lightrec: Add new memory init functions

Lightrec can greatly benefit from having the RAM/BIOS/scratchpad and RAM
mirrors mapped to specific addresses. For the same value of (offset):

- If the RAM is mapped to (offset), the BIOS is mapped to
  (offset + 0x1fc00000) and the scratchpad to (offset + 0x1f800000), the
  generated code will be better;

- If the RAM is also mirrored to (offset + 0x200000), (offset + 0x400000)
  and (offset + 0x600000), the generated code will be even better;

- If the offset is 0x0, the generated code will be even better.

Additionally, the new memory init code will attempt to use huge pages
when possible, in order to greatly reduce the overhead of the MMU.

Add support for mapping emulated RAM to address 0x0

0xff, and all pointers are now checked against a new INVALID_PTR macro.

This is what he had to say about it :
"So, this commit works around/fixes two issues with loading unirom.
There's a fix for logging invalid commands which should be pretty straight forward. The other change is around the FIFO flag.
Not really experienced with debugging/verifying this sort of thing so not feeling really confident the change is "right", though every game I've tried so far still seem to work as expected.
There's still something going on with not having an iso mounted that I haven't quite nailed down. Even having the iso mounted with "lid open" gives a bootable result. Feel like I'm going in circles a bit for something that might be an easy fix. Unirom is technically usable via ISO, but the unirom exe freezes if no iso is loaded"
