Support blocks in asm->wasm global section.
...
The parser can fold together comma separated declarations
into a single block. The AsmWasmBuilder needs to support
this case in order to handle asm.js modules that use this form.

Allow looser heap accesses historically emitted by Emscripten.
...
Older versions of Emscripten appear to emit Asm.js containing:
HEAP8[x] with x in int
As opposed to the spec legal construct:
HEAP8[x>>0] with x in int
As older programs and even benchmarks such as Embenchen
include these constructs, support them for compatibility.

Adding support for asm.js foreign globals.
...
Since wasm has no direct notion of foreign globals,
pass the ffi object on to the AsmWasmBuilder
so that foreign globals can be extracted at module
instantiation time.

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.
