Remove MaskNeeded

Browse Source 
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.

@item MaskExists
The mask specified by the @code{Mask} property already exists.
No @code{MASK} or @code{TARGET} definitions should be added to
@file{options.h} in response to this option record.
The main purpose of this property is to support synonymous options.
The first option should use @samp{Mask(@var{name})} and the others
should use @samp{Mask(@var{name}) MaskExists}.
@item Enum(@var{name})
The option's argument is a string from the set of strings associated
with the corresponding @samp{Enum} record. The string is checked and
