Alex Crichton a16b4dd9a4 Optimize shim generation for structural items ...

This commit removes shims, where possible, for `structural` items.
Instead of generating code that looks like:

    const target = function() { this.foo(); };
    exports.__wbg_thing = function(a) { target.call(getObject(a)); };

we now instead generate:

    exports.__wbg_thing = function(a) { getObject(a).foo(); };

Note that this only applies to `structural` bindings, all default
bindings (as of this commit) are still using imported targets to ensure
that their binding can't change after instantiation.

This change was [detailed in RFC #5][link] as an important optimization
for `structural` bindings to ensure they've got performance parity with
today's non-`structural` default bindings.
