94d0d33e02 Fix single stepping for certain instructions 
Several issues:
1. Several terminal instructions did not stop at the end of a single-step block
2. x64 backend for the A32 frontend sometimes polluted upper_location_descriptor with the single-stepping flag

We also introduce the enable_optimizations parameter to the A32 frontend.

1ebc1895ee 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

2f2a859615 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.
