This PR is about an ICE on SPARC 32-bit with -freg-struct-return.  I didn't 
know that this option was supported on this architecture but apparently it 
was, at least in the 3.x series, so the attached patchlet fixes the ICE.

Tested on SPARC/Solaris (including compat testing), applied on all branches.
