Alex Crichton 15d4338abe Reimplement name disambiguation on overloading
This commit reimplements how we disambiguate function names on overloading.
Previously functions would be first be disambiguated if they had multiple
instances of the same name, and *then* functions would be disambiguated
aftewards by if their arguments expanded to more than one type to generate.

This commit instead collects everything into one list during the first pass.
This one list contains all signatures known for a given name. Later this list is
walked in one pass to generate all methods necessary, expanding names all at
once instead of two steps.

This should improve the naming of methods across multiple functions which also
have optional arguments. Support in this commit is just enough for namespaces,
but following commits will update the strategy for mixins/interfaces.
Additionally only new code was added in this commit which duplicates a lot of
functionality, but subsequent commits will remove the old code that will
eventually no longer be used.
