This makes a few functions used only in shrink-wrap.c static, and
removes their declarations from shrink-wrap.h .

Bootstrapped and regression checked on powerpc64-linux.  Is this
okay for mainline?

	* shrink-wrap.c (requires_stack_frame_p): Make static.
	(prepare_shrink_wrap): Likewise.
	(dup_block_and_redirect): Likewise.
	* shrink-wrap.h: Remove declarations of those functions.
