Fixed a copy pasta error in the implementation of LDD and LDDR. HL should be decremented and not incremented in those instructions.

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).

Add a define in both the source and Makefile for enabling logging of z80 instruction address/cycle counts. Fix Z80 in/out instructions to eliminate assumptions about which registers are stored in native regs. Fix read_16 to not corrupt the low byte when the read has to call into a C function.

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

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
