Fix gcc.c-torture/compile/20010605-1.c on SPARC 32-bit

[Eric Botcazou]

It's a corner case: an unreachable nested function returning a variable-sized 
structure.  The DECL_RESULT of the nested function has no DECL_SIZE in this 
case (I guess that doesn't matter) and the compiler segfaults in the backend.

Tested on SPARC/Solaris 9, applied on the mainline.

	* config/sparc/sparc.c (print_operand) <')'>: Test for a non-null
	DECL_SIZE of DECL_RESULT before evaluating it.
