Fixed a bug in call_raxfallback that would cause the call to be omitted completely in the RAX fallback case. This fixes a crash on OpenBSD and possibly other systems

Fix for Z80 retranslation post alignment rework

Partially working change to do proper stack alignment rather than doing a lame alignment check when calling a C compile dfunction. 68K core seems okay, but Z80 is busted.

Use a new fatal_error function instead of calling fprintf and exit for fatal errors. This new function more gracefully handles the case in which BlastEm was not started from a terminal or disconnected from ther terminal (Windows).

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

Michael Pavone |
Added 2 new functions to gen_x86.c for handling passing args according to the C abi of the host system and adapted the code in m68k_core_x86.c to use that instead of doing everything by hand

Refactor gen_x86 to use an interface more like gen_arm and to remove the need for the caller to decide whether an 8-bit or 32-bit displacement is needed in the rdisp functions. Update m68k_to_x86 to use the new version of the gen_x86 functions and do some minor refactoring there in the process
