The test has a loop that allocates large objects until it gets an
allocation failure. The test then asserts that the subsequent allocation
should also fail. That however does not necessarily hold because the
previously allocated objects may be collected to free up the space.
This change creates a handle for each allocated object. It also
restricts the size of the heap to 20MB to reduce memory consumption.

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.

- NativeContext reads (see also crrev.com/c/2891575)
The second reland (this CL):

will be done separately to avoid further revert chains.
Original change's description:

Also, JSRegExp::StringFromFlags() is introduced to allow for
transforming back from JSRegExp::Flags to the corresponding flag string.
To verify that this implementation is on par with
RegExp.prototype.flags, unittests are introduced under
regexp/regexp-unittest.cc and RegExpBuiltinsAssembler::FlagsGetter()
is updated to include a slow path that calls JSRegExp::StringFromFlags()
through a runtime function.
