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.

This is the second reland of 4683d6fe52
Initial CL: crrev.com/c/2874663
First reland: crrev.com/c/2886861
The first reland fixes Ref construction failures in:
- MapRef::instance_descriptors
- NativeContext reads (see also crrev.com/c/2891575)
The second reland (this CL):
- Adds required infrastructure (e.g. kAssumeMemoryFence) but
without enabling the IsPendingAllocation check. Enabling the check
will be done separately to avoid further revert chains.
Original change's description:
> [compiler] Consider IsPendingAllocation in Ref construction
>
> The logic in JSHeapBroker::TryGetOrCreateData assumes that parts
> of the object are safe to read. In particular, the instance type
> must be readable for the chain of `Is##Name()` type checks.
>
> This is guaranteed if
>
> - a global memory fence happened after object initialization and
> prior to the read by the compiler; or
> - the object was published through a release store and read through
> an acquire read.
>
> The former is protected by the new call to ObjectMayBeUninitialized
> (which internally calls IsPendingAllocation) in TryGetOrCreateData.
>
> The latter must be marked explicitly by calling the new
> MakeRefAssumeMemoryFence variant.
>
> Note that support in this CL is expected to be incomplete and will
> have to be extended in the future as more cases show up in which
> MakeRef calls must be converted to MakeRefAssumeMemoryFence or to
> TryMakeRef.

.. to increase coverage of concurrent inlining, at least in this stress
mode. The common pattern in mjsunit tests is to call
`%OptimizeFunctionOnNextCall(f)` for interesting function `f`. This
explicitly triggers non-concurrent compilation, significantly decreasing
relevant coverage of concurrent inlining.
This CL recovers coverage by spawning an additional concurrent compile
job when 1. --stress-concurrent-inlining is enabled, and 2. the
requested compile mode is non-concurrent. The result of these
additional jobs is discarded.

checks for v8_enable_webassembly=true and v8_enable_lite_mode=false.
As a drive-by, we also do not set the V8_ENABLE_WEBASSEMBLY
preprocessor flag if lite mode is enabled.
The status files are updated by splitting wasm tests from the
"lite_mode" section and checking for "not has_webassembly" instead.
Note that the v8_enable_webassembly=false configuration is not tested
on any bot currently, but I will make sure that all tests keep passing

> This replaces https://chromium-review.googlesource.com/c/v8/v8/+/2376165/.

> Currently JS-to-Wasm calls go through a wrapper/trampoline, built on

> - set "thread_in_wasm_flag" to true
> - convert the arguments from tagged types into Wasm native types
> - calculate the address of the Wasm function to call and call it
> - convert back the result from Wasm native types into tagged types
> - reset "thread_in_wasm_flag" to false.
>
> This CL tries to improve the performance of JS-to-Wasm calls by
> inlining the code of the JS-to-Wasm wrappers in the call site.

> generating code to convert the types for the arguments
> of the Wasm function, when the conversion is not necessary.
> The actual inlining of the graph generated for this wrapper happens in
> the simplified-lowering phase.
