Hello,

The attached deletes the function get_saved_register().  It's been 
superseeded by frame_register() et.al.

Right now, this patch causes a (major) regression.  The sequence:

	$ gdb program
	(gdb) print $pc

gets an internal error.  An examination of a backtrace reveals that the 
code was using `deprecated_selected_frame' and that was NULL.  Before 
committing the attached, I'm going to have to relace a few 
`deprecated_selected_frame's with `get_selected_frame()' (the latter 
throws an error if there really is no frame).

So at this stage, this patch is largely a heads up.  Once I've 
eliminated all the regressions, I'll commit the attached.

Andrew
