The new implementation detects if the input value is outside i32 range
and traps it that case.
The range check is done as follows:
The input value is converted to int32 and then back to float. If the
result is the same as the truncated input value, then the input value
is within int32 range.

Make WasmModule free it's own memory, avoid mixing stack and
heap allocations in tests. This fixes several memory leaks.
Fix several signed compare issues.
Fix several floating point warnings.
Don't setup heap as external, as then the GC can't collect it.
Disable some tests that fail under ASAN.

The code generation for pushing call parameters on the stack does not
distinguish between float32 and float64 parameters because both are
stored in the same registers. Therefore float32 parameters require two
words on the stack. The wasm linkage, however, only considered one word
on the stack for float32 parameters, which caused the problem that
float32 parameters were not located correctly on the stack. I fixed the
problem by considering two words for float32 parameters on the stack.

The test Run_Wasm_StoreMem_offset_oob contained an I64STORE instruction,
which is not yet implemented on 32 bit platforms. I turned off those
parts of the test on 32 bit platforms which contain I64 instructions.

Before this change traps always returned a 32 bit word in tests. With this
change traps return either a 32 bit word or a64 bit word, depending on the size
of the actual return value of the test.
Additionally this CL implements the wasm instructions I64SCONVERTF32,
I64UCONVERTF32, I64SCONVERTF64, and I64UCONVERTF64.

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.
