HACK around apparently problematic return from calling C
...
* HACK ALERT!!! movl(%eax), %eax --or-- movzbl(%eax), %eax
* This pattern appears to be generated in some cases by the compiler. It's not clear to me why it's a problem for
the emulator (not a crash per se, but an emulation lock-up).
* Current suspicion is that there are side-effects in the x86 flags from this instruction/indexing mode which are
copied into the 6502 flags
* Current sample code showing problem (and non-boot of emulator) is f785da40e9
