A32/x64: Create a global_offset optimization for the page table (#507) 
Instead of looking up the page table like:
  table[addr >> 12][addr & 0xFFF]
We can use a global offset on the table to query the memory like:
  table[addr >> 12][addr]

This saves two instructions on *every* memory access within the recompiler.

Original change by degasus in A64 emitter

0046466107 A64/impl: Move AccType and MemOp enum into general IR emitter header 
These will be used by both frontends in the future, so this performs the
migratory changes separate from the changes that will make use of them.

254ab9355e a32_jitstate: Consolidate upper bits of location descriptor into upper_location_descriptor 
Also solves a performance regression initially introduced by b6e8297e369f2dc4758bafe944e51efb8d1a2552,
primarily due to excessively mismatched load/store sizes causing less than optimal load-to-store forwarding.

case. However, we can resolve these cases to make the codebase more
