7c7bcebcc0 (unw_get_save_loc): New variable "nat_bitnr". 
Adjust NaT-bit handling.  Much simpler now.
	Pass NULL as new third argument to ia64_scratch_loc().
	Set save_loc->extra.nat_bitnr to the NaT bit number (or 0
	when not accessing a NaT bit).

50488aece3 (linux_scratch_loc): Add "nat_bitnr"-pointer argument. 
Handle NaT-bit registers by returning not just the
	NaT-word address, but also the NaT-bit number.
(hpux_scratch_loc): Add "nat_bitnr"-pointer argument.
(ia64_scratch_loc): Likewise.
(access_nat): Add "nat_bitnr" argument.  Rename "loc" to "nat_loc".
	Greatly simplify now that we have the NaT-word and the
	NaT bit-number readily available.
(access_reg): Pass NaT-bit number to access_nat().
	Handle scratch NaT-bit registers in a more generic fashion,
	now that we can.  Adjust all calls to ia64_scratch_loc() for
	third argument.
