User defined overloaded operators

New typechecker has no builtin overloaded operators - instead can now
write something in SAIL like:

overload (deinfix +) [id1; id2; id3]

to set up functions id1, id2, and id3 as overloadings for the +
operator. Any identifier can be overloaded, not just infix ones. This
is done in a backwards compatible way, so the old typechecker removes
the DEF_overload nodes from the ast so the various backends never see
it.
