6759942b56 emit_x64_data_processing: Correct bug in ArithmeticShiftRight64 
This branch of this implementation is unused, and thus has not been tested.

backend: x64: block_of_code: Double the total code size. (#595) 
- The current limits are being hit in yuzu with some games (e.g. newer updates of BotW and SSBU).
- Increasing this fixes slow-downs in these games due to code being recompiled.

block_of_code: Allow Fast BMI2 paths on Zen 3 (#593) 
BMI2 instructions such as `pdep` and `pext` have been
known to be incredibly slow on AMD. But on Zen3
and newer, the performance of these instructions
are now much greater, but previous versions of AMD
architectures should still avoid BMI2.

On Zen 2, pdep/pext were 300 cycles. Now on Zen 3 it is 3 cycles.
This is a big enough improvement to allow BMI2 code to
be dispatched if available. The Zen 3 architecture is checked for
by detecting the family of the processor.

fb30922cd1 thumb32: Add supporting decoder entry for PLD (literal) 
LDRH (literal)'s pseduocode indicates that cases where Rt specifies the
PC, that the instruction should be execured as if it were a PLD
instruction.

Curiously, however, within the ARM reference manual, the encodings in the case
that happens doesn't match up.

The bit pattern for LDRH (literal) has bit 21 set to 1, but the encoding
of PLD (literal) has bit 21 set to zero for it's only thumb encoding.
