mips.h: Move variable declarations to end of file and enclose them all in #ifndef...

gcc/
	* config/mips/mips.h: Move variable declarations to end of file and
	enclose them all in #ifndef USED_FOR_TARGET.
	* config/mips/mips.c: Reorder functions into more logical groups,
	and so that callees appear before callers.  Put the targetm
	initializer at the end of the file.  Remove forward static
	declarations where possible.
	(mips_init_builtins): Add "static" to definition.
	(mips_expand_builtin, mips_mode_rep_extended): Likewise.
