[commit] Update PC and FRAME hacks.

[Andrew Cagney <ac131313 at redhat dot com>]

Hello,

Came across more situtations where the target's frame code is directly
writing to the PC and/or FRAME (see avr-tdep.c and alpha-tdep.c) fields
of the frame object.

These functions are to wrap those calls.

For infrun.c, I've also updated things to use one of these newer functions.

committed,
Andrew

2002-12-18  Andrew Cagney  <ac131313@redhat.com>

	* frame.c (deprecated_update_current_frame_pc_hack): Replace
	deprecated_update_current_frame_pc_hack.
	(deprecated_update_frame_base_hack): New function.
	* frame.h (deprecated_update_frame_pc_hack): Replace
	(deprecated_update_frame_base_hack): Declare.
	* infrun.c (normal_stop): Update.
