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

Thanks at skmp for the idea.

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.

6187de7ca7 a32_interface: std::move UserConfig where applicable 
UserConfig instances contain up to 16 std::shared_ptr<Coprocessor>
instances. We can std::move here to avoid performing 16 redundant atomic
reference increment and decrement operations.

Mostly inconsequential on x64, but we may as well signify intent.
