Use ia64_get_abi_marker() instead of directly referencing c->last_abi_marker.
(linux_scratch_loc): When accessing an fp-reg, default to IA64_FPREG_LOC.
	Handle more registers for the Linux interrupt-frame case.
(tdep_access_reg): Use ia64_get_abi() instead of c->as->abi.
	Use ia64_is_big_endian() instead of c->as->big_endian.
