Subject: Small optimization (~2-4%) and whitespace cleanup!

Cleans up a ton of whitespace in cpu.c (like 100KB!) and improves
readability of some massive decode statements.

Added an optimization for PC-relative loads (pool load) in ROM (since
it's read only and cannot possibily change) that directly emits an
immediate load. This is way faster, specially in MIPS/x86, ARM can be
even faster if we rewrite the immediate load macros to also use a pool.
