Include "offsets.h" to get offsets for various structures (such as sigcontext).  Adjust for the fact that the RSE arithmetic is now done on values of type unw_word_t rather than long pointers.

(ia64_scratch_loc): Rename from ia64_get_sigcontext() and expand
	it such that it returns a scratch register location if
	the current frame is not a sigcontext frame.
(ia64_access_reg): Read the address of the personality routine with
	ia64_get() rather than trying to dereference the address
	directly.  When writing the IP or the PR, update the cached
	values, too.
