Currently almost every function that deals with a *_func has to first look up the *moduledata for the module containing the function's entry point. This means we almost always do at least two identical module lookups whenever we deal with a *_func (one to get the *_func and another to get something from its module data) and sometimes several more. Fix this by making findfunc return a new funcInfo type that embeds *_func, but also includes the *moduledata, and making all of the functions that currently take a *_func instead take a funcInfo and use the already-found *moduledata. This transformation is trivial for the most part, since the *_func type is usually inferred. The annoying part is that we can no longer use nil to indicate failure, so this introduces a funcInfo.valid() method and replaces nil checks with calls to valid.
