04805f351b JIT: rewrite pdep implementation 
- use better algorithm that is O(# set bits) instead of O(# total bits)
- eliminate spilling by careful management of our temporaries
- fix nzcv clobber bug (whoops)

e323938173 FEXCore: Fix RCL/RCR shift wraparound behaviour 
This ends up being cleaner to handle outside of
CalculateFlags_ShiftVariable as constant masking is only needed for
RCL/RCR.

407e26bfee FEXCore: Use TMP1-4 for values that need preserving across spills 
The ARM64EC SRA layout will use x0-3 for x86_64 registers, as such any
arguments passed to C ABI functions need to proxy their arguments
through the temporaries and move as appropriate.
