Mark loopfilter C functions as static Clang defaults to C99 mode, and inline works differently in C99. (gcc, on the other hand, defaults to a special gnu-style inlining, which uses different syntax.) Making the functions static makes sure clang doesn't decide to discard a function because it's too large to inline. Thanks to eli.friedman for the patch.
