The flag --trace-ignition-dispatches has been broken for a long time,
since it was not designed to work with bytecode handlers that are
generated ahead of time by mksnapshot. This splits the existing
--trace-ignition-dispatches logic into two separate parts:
1. A gn argument which instructs mksnapshot to include dispatch counting
in the bytecode handlers, and ensures that the Interpreter allocates
the array of counters, and
2. A runtime flag which enables the ignition-statistics extension which
implements the JS-accessible function getIgnitionDispatchCounters().

A spec test (wasm-js/global/value-get-set) requires
WebAssembly.Global.value.set to throw an exception if it is called with
0 arguments. The implementation in V8, however, just checked if the
first parameter is `undefined`. This implementation indeed threw an
exception if 0 arguments were provided, but it also threw an exception
when `undefined` is provided as a parameter. This, however, violates
the spec, because globals can be reset to `undefined`.
With this CL we replace the checking for `undefined` by checking the
length of the arguments that get provided.

This CL adds support for testing web snapshots through mjsunit tests.
To allow for taking and using web snapshots from JavaScript, two
methods, Realm.takeWebSnapshot() and Realm.useWebSnapshot(), are
introduced in d8.
Both of these methods accept a Realm as a parameter, allowing for
mjsunit tests to create and use the snapshot in different realms.
To return the snapshot data, Realm.takeWebSnapshot() creates and
returns a snapshot object with the snapshot data stored as an embedder
field.

There are two different limits for the maximum memory size in
WebAssembly:
1) A 4GB limit which is the same on all platforms, and is observable for
JS programs. It is used to limit the allowed declared maximum size of a
wasm memory.
2) A potentially lower limit (2GB on 32-bit systems, 4GB otherwise)
which can be further limited using a command-line flag. This limit is
used whenever actually allocating or growing a wasm memory. This limit
is not directly observable, but we make sure that no wasm memory will
ever be bigger than this limit.
The second limit is the one we should check against when allocating or
growing memory, while the first limit should be used when validating
a module (or the parameters for WebAssembly.Memory). The compiler can
rely on no memory being bigger than the second limit, which again is
never bigger than the first limit.
This CL adds some more documentation to the two limits, and cleans up
all usages.
This also makes {kPlatformMaxPages} and {kMaxMemoryPagesAtRuntime}
obsolete.

This adds a new status file indicator "HEAVY" to mark tests with high
resource demands. There will be other tests running in parallel,
but only a limited number of other heavy tests. The limit is
controlled with a new parameter --max-heavy-tests and defaults to 1.
The change also marks a variety of tests as heavy that recently had
flaky timeouts. Heavy also implies slow, hence heavy tests are
executed at the beginning with a higher timeout like other slow tests.
The implementation is encapsulated in the test-processor chain. A
new processor buffers heavy tests in a queue and adds buffered tests
only if other heavy tests have ended their computation.

The old code was relying on identical alignment of both the source and
the destination of the Relaxed_Memcpy. This is not always given, thus
check for alignment of both.
