Remove MaskNeeded

2012-03-27  H.J. Lu  <hongjiu.lu@intel.com>

        * opth-gen.awk: Allocated a bit for Mask and InverseMask if it
        hasn't been allocated.  Define a target macro for Mask and
        InverseMask if it hasn't been defined.  Remove MaskExists
        handling.

        * doc/options.texi: Remove MaskNeeded.
