This brings our constants back in line with the changed spec text. We
already use kExprTableGet and kExprTableSet, but for locals and globals
we still use the old wording.
This renaming is mostly mechanical.
PS1 was created using:
ag -l 'kExpr(Get|Set|Tee)Local' src test | \
xargs -L1 sed -E 's/kExpr(Get|Set|Tee)Local\b/kExprLocal\1/g' -i
PS2 contains manual fixes.

We noticed that almost every call site were loading both files,
the split isn't necessary anymore.
In some message tests, removed the absolute line number to allow future
changes.

For the wasm2js wrappers we have an optimization to call a JavaScript
function directly if the signature of the JavaScript function matches
the signature of the WebAssembly import. However, we are not supposed
to do this optimization if the imported function is a constructor,
because constructors can only be called with `new`. With this CL we
do not apply this optimization when the imported function is a
constructor.

Within SanitizeImports it is possible that JavaScript code gets executed
therefore we have to open the CodeSpaceMemoryModificationScope after

This is more renaming work to comply with the naming in the public
design repository. E.g. types are called "value types" and we no longer
refer to ASTs.

There were two bugs, one partly hiding the other one:
1) We generate the ToNumber conversion for each WASM_TO_JS wrapper,
even if the expected return type is void.
2) The return node in the WASM_TO_JS wrapper did not use the effect of
the ToNumber conversion.
This CL fixes both, and adds test cases to check that we do throw an
error trying to convert (e.g.) Symbol to a number, but only if the
return type is not void.
Additional test check that a user-provided valueOf method is actually
called the correct number of times.

Object::GetProperty fails if the given name is a valid array index.

The new tests check that we now accept numbers as module name or
function name in FFI.

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.
