d66bc25749 Automatically bind float math functions
These tend to have one "pretty obvious" definition in JS anyway, so
let's paper over this deficiency in rustc for now by automatically
resolving any imports for these functions.

be368a6570 Don't look up properties in import shims
This'll match more closely what wasm eventually does natively, which is
importing these functions directly and not allowing changing them over time.

c0f2773c4e Don't panic on unsupported exports
It's most likely safe for us to skip exports that we don't yet
support.  Doing nothing will at least not hurt in those cases.

f3c0fc369a Fix compatibility with LLD
Ensure the runtime library is always at least linked as it has important symbols

75837925e9 Find static descriptions inside data nodes
Right now this library only works if the static description is the entire data
node, but with upcoming LLD support everything will be in one data node. This
updates the logic for finding/parsing the program to search through the entire
data node and also know how big a program description is when it finds it.

29771b574c Migrate from a macro to an attribute
This commit migrates from `wasm_bindgen!`-the-macro to
`#[wasm_bindgen]`-the-attribute. The actual mechanics of the macro are
relatively simple in just generating some shims here and there, but wrapping
everything in one huge macro invocation can often seem intimidating as it gives
off this feeling of "oh dear anything can happen here!" Using an attribute
should curb expectations much more greatly of "oh there's just some extra stuff
happening behind the scenes".

The usage is otherwise relatively straightforward and close to what it was
before, but check out the DESIGN.md/README.md changes for more info!

2c7c2e7ae1 Cache more objects in generated JS bindings
Cache the `Uint8Array` and `Uint32Array` views into wasm memory as well as the
instances of `TextEncoder` and `TextDecoder`. Should hopefully help cut down on
gc traffic and otherwise convince the engine to keep these as long-lived
objects.

d5ff725913 Greatly simplify handling of types in Rust
Push the compiler to do trait resolution to figure out what each type is bound
with in JS, and that way we can accept effectively all types (so long as they
implement a trait).

c51a342cb3 Rewrite wasm-bindgen with ES6 modules in mind
This commit is a mostly-rewrite of the `wasm-bindgen` tool. After some recent
discussions it's clear that the previous model wasn't quite going to cut it, and
this iteration is one which primarily embraces ES6 modules and the idea that
this is a polyfill for host bindings.

The overall interface and functionality hasn't changed much but the underlying
technology has now changed significantly. Previously `wasm-bindgen` would emit a
JS file that acted as an ES6 module but had a bit of a wonky interface. It
exposed an async function for instantiation of the wasm module, but that's the
bundler's job, not ours!

Instead this iteration views each input and output as a discrete ES6 module. The
input wasm file is interpreted as "this *should* be an ES6 module with rich
types" and the output is "well here's some ES6 modules that fulfill that
contract". Notably the tool now replaces the original wasm ES6 module with a JS
ES6 module that has the "rich interface". Additionally a second ES6 module is
emitted (the actual wasm file) which imports and exports to the original ES6
module.

This strategy is hoped to be much more amenable to bundlers and controlling how
the wasm itself is instantiated. The emitted files files purely assume ES6
modules and should be able to work as-is once ES6 module integration for wasm is
completed.

Note that there aren't a ton of tools to pretend a wasm module is an ES6 module
at the moment but those should be coming soon! In the meantime a local
`wasm2es6js` hack was added to help make *something* work today. The README has
also been updated with instructions for interacting with this model.
