[PATCH]: PR 11271 Handle reloading of R+R+CONST for any reg

[Richard Earnshaw <rearnsha at arm dot com>]

I originally proposed this some time ago, but never got around to 
installing it.  On Thumb register elimination can lead us to situations 
where a construct of the form

	Reg + Reg + CONST

does not contain a base register.   A patch made to handle a different 
problem on SPARC resulted in this case failing to compile, even though a 
later pass could fix up the problem.

Fixed by forcing find_reloads_address to handle this case for all register 
classes, not just base-register classes.

R.
