Massive data relocation (#295)

Mostly relocating rodata from data/* files to the appropriate
 asm/nonmatching/* files, although there is some plain data
 relocating to be found in here too.

Big change to note is the addition of the code_802AAA70.c file,
 split from memory.c. Based on some padding in the ro/data for
 memory it seems clear that a split is needed, although it is
 not clear that exact spot chosen for the split is correct.
 Still, it gets the file padding for the ro/data and text segments
 correct so it can't be too wrong.

Also included is an update to the asm_processor tool to support
 the .hword directive. I made a PR to the main repo of that
 project with an identical change and it was accepted.
