2aa4656eeb [wasm] Binary 11: WASM AST is now postorder.
[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.

835c5e6beb [wasm] Rework encoding of local declarations.
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.

98d4fbfb2d Add --enable-wasm to wasm tests.
In preparation for switching wasm from a compile to
a runtime option, add the runtime flag to all mjsunit tests.

4c5b3609fd Initial import of v8-native WASM.
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 5981e06ebc, with some formatting fixes and moving some files into src/compiler.
