55bddc767f backend/x64: Touch PEXT/PDEP code 
* Use pext/pdep where not previously used
* Limit pext/pdep to non-AMD platforms due to slowness on AMD
* Use imul/and as alternatives for AMD and non-BMI2 platforms

8b3bc92bce backend/x64: Reduce conversions required for cpsr_nzcv 
The guest program often accesses the NZCV flags directly much less
often than we need to use them for jumps and other such uses.

Therefore, we store our flags in cpsr_nzcv in a x64-friendly format.

This allows for a reduction in conditional jump related code.

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.

93668c24be A64/x64: Create a global_offset optimization for the page table. 
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.

Thanks at skmp for the idea.

3290a9fdc2 common: Remove address_range.h 
The AddressRange structure isn't used anywhere within the codebase, so
this can be removed. Particularly because there's no real appeal/heavy
potential use of it in the future that isn't trivial to add back if
needed.
