I did the implementation with a runtime function. I extracted some code
from the implementation of table.get.

By accident I formatted anyfunc.js. However, since it's an improvement,
I don't want to undo it. I didn't change anything in the older tests
though, I only added new tests at the end.

This CL add decoding and code generation for the table.grow

call. The implementation is quite straight-forward. However,
I did several small cleanups along the way. I hope it's still

On Windows, expanding the stack by more than 4 KB at a time can cause
access violations. This change fixes a few known cases (and includes
unit tests for those), and attempts to make stack expansion more
consistent overall by using the AllocateStackSpace helper method
everywhere we can, even when the offset is a small constant.

On arm64, there was already a consistent method for stack pointer
manipulation using the Claim and Drop methods, so Claim is updated to
touch every page.

{LiftoffCompilationUnit} does not store any data, and has a single
method only. Thus remove it, and replace it by a static function.
This saves one field per compilation unit. We can probably also remove
{TurbofanWasmCompilationUnit} and {InterpreterCompilationUnit} in a
similar way, which I will do in follow-up CLs.

The arm64 ABI defines x18 as a platform register, and as such
platforms may reserve it for their own purposes.

This CL unconditionally removes x18 from the allocatable register list
(previously it was only excluded from arm64 Windows). If, for some
reason, we want to keep x18 allocatable on some platforms, we can
explicitly enable it for specific platforms in the future.

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.

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.

respectively. See

* There are now two indexes for table.copy and memory.copy, one for the
source and the one for the destination table/memory. (see
https://github.com/WebAssembly/bulk-memory-operations/pull/43)

* Reverse the order of the table.init and memory.init indexes, so the
segment index is first and the table/memory index is second. (see
https://github.com/WebAssembly/bulk-memory-operations/pull/45)

movXXXp are replaced with respective movXXXq.

Drive-by cleanup: unified the way we generate movq with other mov instructions.
