[rfa/arm] Eliminate REGISTER_CONVERTIBLE() from ARM

[Andrew Cagney <ac131313 at cygnus dot com>]

Hello,

The attatched eliminates the macros:
	REGISTER_CONVERTIBLE()
	REGISTER_CONVERT_TO_RAW()
	REGISTER_CONVERT_TO_VIRTUAL()
for the ARM target.  Instead REGISTER_VIRTUAL_TYPE() returns what I'm 
*guessing* is the true type of the register.

ok to commit?
