	* config/rs6000/rs6000.opt (rs6000_isa_flags): New flag word to
	replace target_flags that gives us 63 possible switches.
	(x_rs6000_isa_flags): Save area for rs6000_isa_flags.
	(x_rs6000_isa_flags_explicit): Save area for
	rs6000_isa_flags_explicit.
	(rs6000_target_flags_explicit): Delete in favor of
	x_rs6000_isa_flags_explicit.
	(-mpowerpc64): Change all switches that used to be in target_flags
	to now be in rs6000_isa_flags.  In using rs6000_isa_flags, the
	options machinary will generate names of the form OPITON_<xxx>
	instead of TARGET_<xxx> and OPTION_MASK_<xxx> instead of
	MASK_<xxx>.

	* config/rs6000/rs6000-cpus.def (ISA_2_1_MASKS): Move the various
	masks used in rs6000.c here, since they are more logically in this
	file.  Convert from being enums to just #defines, since the types
	of these masks is now HOST_WIDE_INT instead of int.  For
	POWERPC_MASKS, add MASK_SOFT_FLOAT, since the only use case or'ed
	in the mask.  Change the use in rs6000.c not to do the OR of
	MASK_SOFT_FLOAT.

	all uses of target_flags to rs6000_isa_flags.  Change all uses of
	target_flags_explicit to rs6000_isa_flags_explicit.  Change the
	use of MASK_<xxx> to OPTION_MASK_<xxx> that options.h defines when
	we use a secondary flags word.  Save/restore/print the new flags

	Var(...) for all of the isa switches, the options machinery now
	uses OPTION_MASK_<xxx> instead of MASK_<xxx> for the mask name.
	Use #define to map the old name into the new name.  For switches
