[patch] Zap some not-needed regcache interfaces

[Andrew Cagney <ac131313 at cygnus dot com>]

Hello,

In getting ready for the next regcache patch, I found I could simplify 
things a little and eliminate a number of the regcache interfaces I'd 
added and was using on the branch.  Applying the `keep it simple s..' 
rule I've removed the redundancy.

committed,
Andrew
