History
Kevin Lawton 3bfeab23c9 Split out JZ/JNZ instructions from JCC because they were called 
so frequently.
Coded asm() statements for INC/DEC_ERX() instructions.
Cleaned up the iCache a litle including a bug fix.  The
  generation ID was decrementing the whole field including
  some high meta bits.  That could roll over after 1 Billion
  cycles.  I know only decrement if the field is valid, to
  save the write.
I implemented inline functions which can serve the value of
  the arithmetic flags if they are cached, and redirect to
  the lazy_flags.cc routines if not.
Most of this was just prep work for adding more asm() statements
  for native eflags processing when on x86.
