Previously these were being included as both imports and
exports, with the import being satisfied by the export
(or some strong symbol) at runtime. However proved
unnecessary and actually complicated linking as it meant
there was not a 1-to-1 mapping between a wasm function
/global index and a linker symbol.

Summary:
This manifested itself in lld since it meant that weak
symbols were not appearing in archive symbol tables.

- Add test that preproduces the crash.

Model weakly defined symbols as symbols that are both
exports and imported and marked as weak. Local references
to the symbols refer to the import but the linker can
resolve this to the weak export if not strong symbol
is found at link time.

Previously we were generating a void(void) function type
for a weak alias. Update the weak-alias test case to
catch this.
