      [wasm] Implement an interpreter for WASM. · e4bb7ff9
      titzer authored 
      This interpreter directly decodes and executes WASM binary code for
the purpose of supporting low-level debugging. It is not currently
integrated into the main WASM implementation.

      [wasm] Binary 11: WASM AST is now postorder. · 2aa4656e
      titzer authored 
      [wasm] Binary 11: br_table takes a value.
[wasm] Binary 11: Add implicit blocks to if arms.
[wasm] Binary 11: Add arities to call, return, and breaks
[wasm] Binary 11: Add experimental version.

This CL changes the encoder, decoder, and tests to use a postorder
encoding of the AST, which is more efficient in decode time and
space.

      [Wasm] Convert many of the fixed-size values to LEB128. · 78f6f838
      binji authored 
      This CL modifies the following to be LEB128:
* Function table indices
* Import table signature indices
* Export table function indices
* Function signature param count
* br/br_if break depth
* br_table target count
* block/loop expression count

Still to do:
* Import/export names (LEB128 count + inline data)
* Data segments (LEB128 offset + size + inline data)
* Function header stuff (should seperate into function sig and body sections)
* Memory access alignment + offset (still discussing)

      [wasm] Rework encoding of local declarations. · 835c5e6b
      titzer authored 
      Local declarations were previously encoded as an optional set of
4 uint16 values as part of the function declaration. This CL
implements the current design of moving these declarations to
a list of pairs of (type, count) that is part of the body.
