ef3c733810 [wasm] Implement the table.grow instruction
This CL add decoding and code generation for the table.grow
instruction. For code generation we just generate a runtime
call. The implementation is quite straight-forward. However,
I did several small cleanups along the way. I hope it's still
acceptable. I could also split out some cleanups into separate
CLs.

c7627bbc8a [wasm] Refactor WasmTableObject::Grow
This CL refactors WasmTableObject::Grow to make it usable for the
table.grow instruction of WebAssembly.

The refactored version of WasmTableObject::Grow does additionally:
* Check if growing is possible
* Grow the FixedArray backing store of the table and initialize the new
  fields.
* Calculate the return value of WasmTableObject::Grow.

a) the --wasm-trap-handler-fallback flag,
b) the distinction between soft and hard address space limit,
c) methods to check whether memory has guard regions (it will always
  have them on 64 bit architectures),
d) associated runtime functions,
e) the trap handler fallback tests,

34c8443c88 [wasm][bulk-memory] Check segment bounds lazily
The bulk memory proposal changed behavior of segment initialization
during instantiation. Previously, all segments would be bounds-checked,
after which the segments would be initialized.

The bulk memory proposal removes the up-front check, and always
initializes active segments in order, starting with element segments and
then continuing with data segments. Each active segment is initialized
as-if they were being initialized with the `memory.init` and
`table.init` instructions, so an out-of-bounds initialization may still
modify the memory or table partially.

af1988f1e4 [wasm] Enable bulk-memory by default
See intent to ship here: https://groups.google.com/forum/#!topic/v8-users/zM05lYEBVog

wasm-module-builder.js is also changed to use the new syntax for specifying a table
index in an element segment. In the MVP, the table index was always zero. The
reference types proposal adds support for multiple tables, and originally used this
value to specify a non-zero table index. The bulk memory proposal needed a way to
specify a passive element segment, so it re-purposed the table index as a flags field
and uses a different field for the table index.

9010424ff5 Reland "[wasm] Implement table.init for interpreter"
This is a reland of 63608968b6

The previous CL failed on Windows, but it was a general bug. The
dropped_elem_segments was not being set on the instance properly in
cctests, so`table.init` instructions would fail by reading uninitialized
data.

I took this opportunity to also add an implementation of
`elem.drop` in the interpreter, and ported the JS tests for those too.

> [wasm] Implement table.init for interpreter

> This also fixes CheckCallViaJS when a trap occurs. In that case, the

We no longer directly store reference values on the stack, but maintain
a separate "reference stack" on the GC'ed heap. This will ensure the GC
traces such references properly.

The new {StackValue} safety wrapper makes sure all use-sites that access

reference values.

8cbcae37db [wasm] Handle rejected input promise in WebAssembly.compileStreaming
In the implementation of WebAssembly.compileStreaming and
WebAssembly.instantiateStreaming, we did not handle the case where the
input, which is a Promise, gets rejected. When this Promise got
rejected, the Promise returned by compileStreaming remained pending
forever.

With this CL, the rejection object of the input Promise gets forwarded
to the result Promise.

I also extended the --wasm-test-streaming flag to provide
WebAssembly.compileStreaming and WebAssembly.instantiateStreaming
in d8. The difference to the Chrome versions of these function is
that d8 does not know about Response objects. That's why in d8
compileStreaming and instantiateStreaming expect a Promise to an
ArrayBuffer or a TypedArray and not to a Response object.

2d9ec0a420 Reland: [wasm][anyref] Add support of call-indirect for multiple tables
The reason for the revert was that Liftoff did not bail out on indirect
calls to tables other than table 0. Whenever the Liftoff code got
executed, the test would fail.

Original message:
With this CL it is possible to use any anyfunc table in call-indirect,
not just the first table.

The current implementation is based on runtime calls. This is just an
initial implementation which should be replaced by a
dispatch-table-based eventually. However, this implementation allows
us to move forward with the anyref proposal implementation.

eb1d2d7098 [wasm] Make error messages deterministic
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.
