702: Add support for shared memory in Wasm. r=nlewycky a=nlewycky
Add support for memory regions with the shared flag. These are part of the threads proposal.
- Add new `--enable-threads` flags and pass it through to wasmparser.rs and wabt (for .wat files).
- Enable `--enable-threads` when parsing spectests. Enables the shared memory region in `simd.wast`.
- Adds `atomic.wast`, the spec test for the threads proposal. With the LLVM backend, all tests pass.
- Removes the `runtime-core/src/memory/static_` directory since there's no need for it to include two implementations. We use the same implementation of static memory for shared and unshared static memory.
- Implements the atomic instructions in the LLVM backend. However, `atomic.load` and `atomic.store` are provided **with no atomicity.** The rmw and cmpxchg instructions are sequentially consistent.
- `atomic.notify` and `atomic.wait` are unimplemented.
