CR bits are now resident in registers instead of being baked into the instruction definitions. Same for XER SO, and LWARX reservation EA and value.
Reworked LWARX/STWCX, CRxx ops, compare and branch instructions. As well as RC bit handling. Not all CR-related instructions are reimplemented yet.
Introduced atomic_cmp_store operation to allow implementing STWCX in architecture agnostic IML
Removed legacy CR-based compare and jump operations
Carry bit is now resident in a register-allocated GPR instead of being backed directly into IML instructions
All the PowerPC carry ADD* and SUB* instructions as well as SRAW/SRAWI have been reworked to use more generalized IML instructions for handling carry
IML instructions now support two named output registers instead of only one (easily extendable to arbitrary count)
Storing the condition result in a register instead of imitating PPC CR lets us simplify the backend a lot. Only implemented as PoC for BDZ/BDNZ so far.
Intermediate commit while I'm still fixing things but I didn't want to pile on too many changes in a single commit.
New:
Reworked PPC->IML converter to first create a graph of basic blocks and then turn those into IML segment(s). This was mainly done to decouple IML design from having PPC specific knowledge like branch target addresses. The previous design also didn't allow to preserve cycle counting properly in all cases since it was based on IML instruction counting.
The new solution supports functions with non-continuous body. A pretty common example for this is when functions end with a trailing B instruction to some other place.
Current limitations:
- BL inlining not implemented
- MFTB not implemented
- BCCTR and BCLR are only partially implemented

Removes the -DPUBLIC_RELEASE flag. Cemu's debug asserts are now only enabled if the build configuration is Debug. Similarly, on Windows the console is only shown for Debug builds.
