prototype for 'resolve_typebound_function' [-Werror=missing-prototypes]
cc1: all warnings being treated as errors
This is because r182754 (PR 46262 + 46328 + 51052 fix) deleted the 'static' for
resolve_typebound_function, even though nothing outside of resolve.c calls it,
and there is no previous prototype in scope.
Adding the 'static' back allows bootstrap to complete.
Yet another error missed due to the build-everything-with-c++-by-default
change.
