History
Kevin Lawton b742ccec7e Changed eflags accessors for get_?F() to use (val32 & (1<<N)) instead 
of (1 & (val32>>N)), and added a getB_?F() accessor for special
  cases which need a strict binary value (exactly 0 or 1).  Most
  code only needed a value for logical comparison.  I modified the
  special cases which do need a binary number for shifting and
  comparison between flags, to use the special getB_?F() accessor.

Cleaned up memory.cc functions a little, now that all accesses
  are within a single page.

Fixed a (not very likely encountered) bug in fetchdecode.cc (and
  fetchdecode64.cc) where a 2-byte opcode starting with a prefix
  starts at the last offset on a page.  There were no checks
  on the segment overrides for a boundary condition.  I added them.

The eflags enhancements added just a tiny bit of performance.
