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.

to a stacked register. We can't use ia64_get_stacked() here because
c->rbs will, in general, be different from the frame in which the
register was saved.
(Logical change 1.173)
(linux_scratch_loc): Add support for new pt_regs layout.
(access_nat): Check last_abi_marker instead of sigcontext_addr and
address-space ABI.
(Logical change 1.91)
support for HP-UX.
(access_nat): Check for uc-location and pass it on to ia64_put()/ia64_get() if
it is. Handle NaT-bit-saved-in-scratch-register only for Linux.
(ia64_access_reg): Change dprintf() into debug() statement.
(ia64_access_fpreg): Move fph-partition initialization code to ia64_scratch_loc().
Change dprintf() into debug() statement.
(Logical change 1.87)
IP is outside the range of the old procedure.
When writing one of the exception argument registers, track the update
in c->eh_valid_mask.
