a52967680e Allow bitwise operators to convert from intish to int in heap ops. 
We previously supported use of bitwise operations to convert
from intish to int, but use of kAsmInt in some places and kAsmIntQ
in others prevents this from working with heap accesses.
Switch to use kAsmIntQ where appropriate (even though intish_ != 0
in principle captures the superset of these cases),
as it's more conservative (and uses types.h better).

c8c5b3fddf Allow negative literals in asm->wasm non-conversion operations. 
This allows expressions like:
(x + y) & -1
[intish] & [signed]

The previous conversion condition was too strict (intended to
forbid non-int expression conversion). Expressing in
a different way.

0dd24015fb Allow constant multiply both ways. 
asm.js permits both:
int * constant
constant * int

It does not, however, allow intishes in multiplies.

7e805faa30 Allow intish and floatish to be coerced by heap assignment. 
When assigning to an integer view of the heap an intish
value does not need to be collapsed with |0.
Similarly a floatish value does not need to be collapsed with
fround when assigned to a float view of the heap.
i32[0] = i32_1 + i32_2;  // ok
f32[0] = f32_1 + f32_2;  // ok

However, floatish values cannot be safely assigned to double
arrays.
f64[0] = f32_1 + f32_2;  // not ok

into a single block. The AsmWasmBuilder needs to support
this case in order to handle asm.js modules that use this form.

f9ee14e519 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.

keeping alive a second interface seems clunky.

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.
