Compilation only stores whether an error has been found, but not the
exact error or it's location. This is generated by running a validation
pass once all wire bytes have been received.
This unifies error messages by removing one more location where we
generate compilation error messages, and makes it deterministic because
a) we always report the error in the first failing function, and
b) if names are present, the error message will always contain the
function name.

In particular, remove {toUint8Array} method and make {toBuffer} return
a {Uint8Array} view to the buffer like before
https://crrev.com/c/1508352. Also, the returned view does not need to be
another copy of the bytes, it can really just be a view.
As a follow-up, this requires the test-only DeserializeWasmModule
runtime method to receive the wire bytes as Uint8Array, and also
requires the {IsWasmCompileAllowed} callback to handle
{ArrayBufferView} (like chromium's version already does).

According to the wasm js-spec, the table index can be uint32. The
implementation in our implementation expected an int though. We did not
check for the int overflow.
I replaced the throwing of the exception in WasmTableObject::Get to use
the ErrorThrower instead of throwing the exception with Isolate::Throw
directly. The reason is that I see with other CL's that I have to throw
several errors, and I don't want to introduce a new message and
MessageId for every error. Moreover, the ErrorThrower is a standard way
in wasm to throw errors. It feels right to throw the error the same way
here.

We have to create WasmExportedFunction objects for any WebAssembly
function which may escape a WebAssembly instance. Up until now we
created these WasmExportedFunction objects eagerly during instantiation
time: for any exported function, and any element in an exported table we
create such an object.
With the anyref proposal, the table.get instruction can allow any
function in a table to escape its instance. Therefore we would have to
create a WasmExportedFunction object for any function which is put into
a table.
With this CL we create WasmExportedFunctions for table entries lazily.
We initialize tables with placeholders consisting of the instance and
the function index. If we encounter a placeholder in table.get, we
create the WasmExportedFunction for the expected function to return it.

The assertThrows and assertDoesNotThrow methods expect either a
function to execute, or a string to eval. In several tests however we
accidentally passed the *result* of the statement to be tested instead
of the code.
This CL adds check to catch such error early, and removes wrong uses.
In most places, we do not need to use assertDoesNotThrow anyway,
because exceptions are handled as test failures.
Drive-by: Unify catch syntax in mjsunit.js and make sure to propagate
MjsUnitAssertionErrors correctly.

This CL revises some of our error messages to be more precise or more
aesthetically appealing.

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.

Changes made to the Wasm module builder:
- Create emit_u64v for emitting a LEB128 that conceptually represent
an 64-bits integer.
- Differentiate toBuffer and toUint8Array for returning respectively
ArrayBuffer and a Uint8Array.
- Moved wasmF32Const and wasmF64Const functions because we can take
advantage of the existing cached conversion buffers. Also, declaring
them in the constants file will collide with the module-builder since
they are loaded in the same scope.
- The byte_view buffer (used by some conversions to bytes) switched from
Int8Array to Uint8Array.
Changes made to the Wasm contants:
- Add a new kSharedHasMaximumFlag flag for shared memory with a maximum
value.

Anyref parameters can exist across GC runs. Therefore the GC has to
know where anyref parameters are on the stack so that it can mark them
in its marking phase, and update them in the compaction phase.
Already in a previous CL we grouped all anyref parameters so that they
can be found more easily in a stack frame, see
https://crrev.com/c/1371827. In this CL we implement the stack scanning
itself.
Note that anyref parameters are not scanned while iterating over the
caller's frame (to which they actually belong), but while iterating
over the callee's frame. The reason is that with tail-calls, only the
callee knows how many tagged stack parameters (aka anyref parameters)
there are.
