      [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.

      Initial import of v8-native WASM. · 4c5b3609
      titzer authored
      As discussed in person, this adds the code from v8-native-prototype into
      V8 proper, guarded by GYP flags that do not build the code by default.
      Passing wasm=on to 'make' or setting v8_wasm as a GYP flag activates
      building of this code.
      
      An additional header file is added to and exported from the compiler
      directory, src/compiler/wasm-compiler.h. This exposes a limited interface
      with opaque Node and Graph types to the decoder to build TF graphs, as
      well as functions to compile WASM graphs.
      
      The mjsunit tests added are blacklisted because they fail without the
      WASM object exposed to JS, which is also disabled by the build config
      option.
      
      This corresponds closely to https://github.com/WebAssembly/v8-native-prototype/commit/5981e06ebc9b1e578831d03100f17ebb77970ee0, with some formatting fixes and moving some files into src/compiler.
