Also avoid changing --turbo-filter when --no-opt is set, and instead
explicitly check both the FLAG_opt and FLAG_turbo_filter in
GetOptimizedCode to check whether optimization is disabled.

Note that the previous prototype for catch and throw have been marked

This improves the general Array constructor call performance (w/o
usable AllocationSite feedback) in TurboFan by ~2x, i.e. for example
invoking the Array constructor like this
var a = Array.call(undefined, n);
instead of
var a = Array(n);
such that the CallIC doesn't know that it's eventually calling the
Array constructor.
It also thus changes the single argument Array constructor to always
return holey arrays. Previously the single argument case for the Array
constructor was somehow trying to dynamically detect 0 and in that case
returned a packed array instead of a holey one. That adds quite a lot
of churn, and doesn't seem to be very useful, especially since this
might lead to unnecessary feedback pollution later.

This is the next step towards faster Map and Set iteration. It
introduces the appropriate instance types for Map and Set
iterators (following the pattern for Array iterators) and migrates
the following builtins to the CodeStubAssembler:
- Set.prototype.entries
- Set.prototype.values
- Map.prototype.entries
- Map.prototype.keys
- Map.prototype.values
- %SetIteratorPrototype%.next
- %MapIteratorPrototype%.next
This already provides a significant performance boost for regular
for-of iteration of Sets and Maps, by a factor of 5-10 depending
on the input. The final step will be to inline some fast-paths
into TurboFan.
Drive-by-fix: Remove obsolete %IsJSSetIterator and %IsJSMapIterator
intrinsics and runtime functions.

This CL refactors the WasmMemoryObject and WasmInstanceObject classes to
use WeakFixedArray instead of using a doubly-linked list of instances. This
simplifies the lifetime management of instances by not requiring them to
be unlinked from this list upon GC. It also simplifies the iteration over
the instances using a given WasmMemoryObject.
Note that, contrary to my naive assumption at the outset, it is still necessary for the InstanceFinalizer (called upon a WasmInstanceObject death) to unlink itself from a WasmMemoryObject's instances list, due to finalizer ordering.

If a thin string can be dereferenced for StringConcat we still need to check
whether the dereferenced string is a sequential string itself (it could be
an external string).

Tsan figured out that I called compilation_units_.empty() outside a
lock.
Original message:
This CL adds a new function {InitializeCompilationUnit} to initialize
a single compilation unit and not just all compilation units at once.
This is necessary for streaming compilation eventually. This also
required some refactoring on how the working queue for compilation units
works. Previously the synchronization was done with an atomic counter,
now it is done with a lock. Note that the code to finish compilation
of a module still only works if the working queue gets only empty when
all work is done. I plan to change this in a different CL.
Since the code would not be tested without streaming compilation, I added
an experimental flag and a test to test the new code.

This CL adds a few transformations that clean up the set of reported
source ranges. Duplicates, empty, and uncovered ranges are removed, and
nested/consecutive ranges are merged if possible.

This is a preliminary step before we stop swapping maps in the bootstrapper
(strict/sloppy map with writable prototype <-> readonly prototype).
