[PATCH] Generic register_virtual_size function.

[Michael Snyder <msnyder@cygnus.com>]

This idea occurred to me after looking at Andrew's 
generic version of register_raw_size:

2001-12-10  Michael Snyder  <msnyder@redhat.com>

	* arch-utils.c (generic_register_virtual_size): New function.
	* arch-utils.h: Export generic version of register_virtual_size.
	* gdbarch.sh (REGISTER_VIRTUAL_SIZE): Use new function as default.
	* gdbarch.c: Regenerate.
