53a9cc3950 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
