cc1: all warnings being treated as errors
make[3]: *** [ipa-inline-transform.o] Error 1

r186832 renamed cgraph_preserve_function_body_p and moved it to
ipa-inline-transform.c, but in that process it ended up (a) non-static, and (b)
without a separate prototype, and that triggers -Werror=missing-prototypes.

preserve_function_body_p is only used in the same file it's defined in.  Making
it 'static' restores bootstrap for me.
