Move target CPP macro handling to C file and add __VIS/__VIS__.

	* config/sparc/sparc-c.c: New file implementing sparc_target_macros,
	which will now define __VIS and __VIS__ when -mvis is enabled.
	* config/sparc/t-sparc: Likewise.
	* config.gcc: Add sparc-c.o to c_target_objs and cxx_target_objs,
	and add t-sparc to tmake_file for all sparc targets.
	* config/sparc/sparc-protos.h (sparc_target_macros): Declare.
	* config/sparc/sparc.h (TARGE_CPU_CPP_BUILTINS): Call it.
