This CL is the start to implement reference types support in Liftoff.
As a first step this CL implements the ref.null instruction, and allows
reference types as return values. This allows register allocation to be
extended to support reference types, and also adds an easy way to get a
reference type value for tests. Additionally with ref.null we don't have
to worry about garbage collection because 'null' is an immovable object
and therefore does not have to be scanned by the GC.

The cctests need to simulate full pages, however the calculation of the
remainging available space is wrong causing an assertion when we change
the V8 page size to 512K:

    $ cctest test-array-buffer-tracker/ArrayBuffer_PagePromotion

    #
    # Fatal error in ../../test/cctest/heap/heap-utils.cc, line 94
    # Check failed: padding_size <= overall_free_memory || overall_free_memory == 0.

The reason is:

  - On startup, we register a scavenger observer on the new space. The
    observer is set to trigger when the new space capacity is at 80% by
    default.

  - On linux, the initial capacity of the new space is 512K, so the
    scavenger observer will be placed at 80% of 512K, which will either
    be in the second page of the space if the page size is 256K, or in
    the first page if the page size is 512K.

  - When placing the observer, if the observer hits the first page, we
    lower the allocation limit (see `ComputeLimit()`). This makes sure
    the observer isn't skipped by allocations inlined in generated code.

However, when we simulate filling the current page, we compute the space
left in the current page by comparing the top with the `page_high()`
rather than `limit()`. This was done so the tests would also work when
inlined allocations are disabled. If we don't look at the `limit()`, we
don't take the observer into account and fill more space than is
available, triggering the assertion.

This can also be reproduced by reducing the % at which the scavenger is
triggered so that it hits the first page instead of the second when the
page size is 256K, for example passing --scavenge-task-trigger=10.

With WebAssembly streaming compilation it is possible that FinishStream
indirectly calls AbortStream. This had the effect that while
FinishStream fulfilled the promise, AbortStream disposed the promise
by removing the compile job from the wasm engine and thereby deallocated
AsyncCompileJob and all the state that belongs to it. Without that
state, FinishStream could not finish fulfilling the promise correctly.

With this CL the streaming decoder remembers that the stream has
already been finished. When the stream has been finished, all calls to
Abort get ignored.

The regression test for this issue requires the Chrome embedding, see

This bumps the engine-wide limit for generated machine code from 1GB to
2GB. This will allow compiling (and debugging) bigger modules, as they
occur particularly in the debugging use case because the module will be
unoptimized then.

The limit per allocated code space is left at 1024MB (1GB), so a module
will need to allocate two separate code spaces to make use of the full
2GB code space.

Marking on allocation assumes a non-empty stack. Thus marking on
allocation will not finalize even if it runs out of work (we prefer
to finalize in a non-nestable task with no stack).
Instead it will schedule another marking task and delegates
finalization to the next marking task.

 Unreachable();
 Goto(&some_label);  // Never reached but generates useless code.

This CL improves usability by automatically merging Unreachable nodes
to the end node, and terminating current effect/control. The updated
pattern is just

 Unreachable();

or in cases where Turboprop must maintain a schedule:
