[RFA] regcache pseudo-reg tweak

[Michael Snyder <msnyder@cygnus.com>]

Andrew, 

I think you left out an "else" when you made this change in december.
We must not call target_[fetch/store]_register with a pseudo-register, 
or they will choke.  By definition, a pseudo-register is one that 
cannot be fetched from the target.

Remote_fetch_register, for instance, aborts on this.

	* regcache.c (fetch_register): Don't call target_fetch_register
	for a pseudo_register.
	(store_register): Don't call target_store_register for a
	pseudo_register.
