Restore Sparc build.

gcc/

	* config/sparc/sparc.h (INITIAL_ELIMINATION_OFFSET): Split out to
	new function sparc_initial_elimination_offset.
	* config/sparc/sparc.c (sparc_initial_elimination_offset): New
	function.
	* config/sparc/sparc-protos.h (sparc_initial_elimination_offset):
	Prototype it.
