Fix a bunch of assumptions about which Z80 registers are stored in native registers to make the x86-32 build less broken

Make sure z80_save_reg does nothing when there is no register in the reg field of the instruction. This fixes a bug that corrupted SP in the MDEM 2011 demo

Call z80_handle_deferred after generating an insruction handler so that instructions like rst work correctly

Save PC to context struct when syncing Z80 at instruction start. This fixes saving savestates and probably the Z80 debugger as well

Made the Z80 core more contained by refactoring some code in blastem.c into z80_to_x86.c

All cycle counters are now based off the master clock. This seems to have messed up Z80 interrupt timing (music in Sonic 2 is too slow for instance), but things are generally working

In theory, the Z80 core should work on 32-bit builds now; however, I suspect there is some code that cannot deal with most of the Z80 registers not having a native register so more work will be needed

Added functions to gen_x86 for saving and restoring callee save registers to better abstract over ABI differences between x86 and x86-64

Use SZ_PTR instead of SZ_Q in Z80 core for 32-bit compat

Sync Z80 when taking an interrupt so that int_cycle gets updated

Fix flags for rra, rrca, rla and rlca. Fix timing for rr, rrc, rl and rlc when using IX or IY. Fix access to I and R registers (R still needs to be made 7-bit though). Fix flags for ld a, i. The fix for access to I fixes PCM playback in Titan Overdrive and music playback in Crackdown.

Temporarily comment out code to translate Z80 instructions in place as in rare cases it can stomp the next instruction if a branch goes from a short from to a long one
