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.

Calls with a spread expression in a non-final position get transformed
to calls to Reflect.apply. This transformation is currently done in
the parser, which does not compose well with other features (e.g.
direct eval checking, optional chaining).

Do this transform in the BytecodeGenerator instead.

Implements https://github.com/tc39/ecma262/issues/2034

Currently the token sequence `for (async of` is ambiguous. It can be the
prefix for either `(async of => {};;);` or `for (async of foo);`. This
CL disallows the token sequence.

Note that `for await (async of` is still allowed, since there is no
C-style `for await (;;)`, and thus no ambiguity.

Making TA elements configurable has interaction with delete. While
the elements are configurable, they are only "deletable" via detaching
the underlying ArrayBuffer, not via `delete`. That is, `delete ta[idx]`
for an in-bounds `idx` still returns false.
