74f92f21da Simplify, speed-up correct-context ObjectObserve calls 
The original patch which ensured that Object.observe did allocations in the correct context regressed performance about 12%. This patch gets back most of that (about 11%) by simply returning the correct function which is then directly callable from JS, rather than by making the call from the runtime function. A side-effect is that their implementation is shorter.

20eeff9ae4 Allow microtasks to throw exceptions and handle them gracefully 
If the embedder calls V8::TerminateExecution while we're running microtasks, bail out
and clear any pending microtasks.

All other exceptions are simply swallowed. No current Blink or V8 microtasks throw, this
just ensures something sane happens if another embedder decides to pass a throwing
microtask (or if ours unexpectedly throw due to, e.g., stack exhaustion).

7ac892c8bd Establish distributivity for type union & intersection 
This requires introducing proper bounds on all leaf types, so that intersection between bitsets and these types can be accurately represented. Extending a union also becomes more involved.

(On the upside, the modified union/intersect algorithm would now allow support for proper variance for function types.)

Not sure if it is worth landing this. Distributivity isn't really a crucial property for our use cases. It seems fine if intersection is slightly lossy.

3d0bf69cd8 Attempt no. 3 to fix Heap::IsHeapIterable and HeapIterator. 
Now we remember new space's top pointer after the last GC to find out if there was a new space allocation since the last GC.

Unfortunately, this not completely safe - the debugger has a callback hook (that can call to JS) at the end of the GC epilogue that can in theory allocate and possibly make the heap non-iterable. We can only hope this does not happen.

fired twice for a code object. When the event was processed for the first

As a result when a cpu profile sample falls into the region it missed the

70c3a714a1 ES6 Map/Set iterators/forEach improvements 
This changes how Map/Set interacts with its iterators. When the
underlying table is rehashed or cleared, we create a new table (like
before) but we add a reference from the old table to the new table. We
also add an array describing how to transition the iterator from the
old table to the new table.

When Next is called on the iterator it checks if there is a newer table
that it should transition to. If there is, it updates the index based
on the previously recorded changes and finally changes itself to point
at the new table.

With these changes Map/Set no longer keeps the iterators alive. Also,
as before, the iterators keep the underlying table(s) alive but not the
actual Map/Set.

This avoids the appearence of a leak due to storing a JSObject
as the microtask_state in the strong root list, and allows callers
to call Isolate::RunMicrotasks() without having any v8::Context
available (as at least Blink has interest in doing).

The queue is now a strong root, represented as a FixedArray of JSFunctions
(or empty_fixed_array, if it's empty); it doubles in size when it needs to grow.
The number of elements in the queue is stored in Isolate::pending_microtask_count().

Traditionally, we cross compile a snapshot iff the serializer is enabled.
This will change in the future.

Changes:
 - CpuFeatures probing is done once per process, depending on whether we
   cross compile.
 - CpuFeatures are consolidated into the platform-independent assembler.h
   as much as possible.
 - FLAG_enable_<feature> will only be checked at probing time (already the
   case for ARM).
 - The serializer state is cached by the MacroAssembler.
 - PlatformFeatureScope is no longer necessary.
 - CPUFeature enum values no longer map to CPUID bit fields.

11b8551f60 Parser / PreParser: Simplify error message arguments. 
In some places, we pretended that there can be multiple arguments, though in
practice there was only one. In other places (most importantly, PreParser), we
only handled one argument. (This means that we were not able to produce a
multi-argument error inside a lazy function anyway.)

This CL makes it clear that there is ever only one argument.

e876dab9ad ARM64: Fix and improve MacroAssembler::Printf. 
- W-sized values passed to Printf are now handled correctly by the
    simulator. In AAPCS64, int32_t and int64_t are passed in the same
    way, so this didn't affect non-simulator builds.
  - Since Printf now records the type and size of each argument, it is
    possible to mix argument types.
  - It is now possible to print the stack pointer. There is only one
    remaining restriction: The `csp` register cannot be printed unless
    it is the current stack pointer. This is because it is modified by
    BumpSystemStackPointer when the caller-saved registers are
    preserved.

Even although the Arm64 specification specifies that csp

implementations show poor performance.

Also makes the following change:
 - Enable CPU support for arm64 to enable probing of cpu implementer and cpu part.
 - Add ALWAYS_ALIGN_CSP CpuFeature for Arm64 and set it based on runtime probing of the cpu imp

67ff68783a Arm64: Fix check errors on Arm64 debug after r21177. 
r21177 added extra AssertStackConsistency() checks which
increased code size on debug and caused the assembler buffer
to be too large.  Increased some of these buffers to
compensate.

Also, ProfileEntryHoolStub could use the wrong number of
instructions for kProfileEntryHookCallSize depending upon
whether debug code was being emitted or ALWAYS_ALIGN_CSP was
enabled.  Fixed this by taking ALWAYS_ALIGN_CSP into account
and ensuring that no debug code is emitted during
MaybeCallEntryHook().

3274485c50 Store JSGlobalProxy's identity hash directly on the proxy itself 
Previously, the hash was stored on the underlying global object, since
it was stored in the hidden property table. This patch moves to an
implementation modeled on JSProxy, adding a new 'hash' field to JSGlobalProxy.

This allows storing the global proxy in a Map, Set, WeakMap, or WeakSet and
accessing it even after the proxy has been attached to a new global, which
is Firefox's current behavior and was the consensus of a recent thread on public-script-coord:

98cd283399 Remove symbol preparse data altogether. 
Removing it seems to be a clear win on mobile: producing symbol data makes cold
parsing 20-30% slower, and having symbol data doesn't make warm parsing any
faster.

Notes:
- V8 used to produce symbol data, but because of a bug, it was never used until
recently. (See fix https://codereview.chromium.org/172753002 which takes the
symbol data into use again.)
- On desktop, warm parsing is faster if we have symbol data, and producing it
during cold parsing doesn't make parsing substantially slower. However, this
doesn't seem to be the case on mobile.
- The preparse data (cached data) will now contain only the positions of the
lazy functions.

5ea893074c Fix ObjectNotifierPerformChange leak after r21126 
Due to overlapping names of natives and runtime functions, the wrong
context was used for Notifier.prototype.performChange. The leak test
has been augmented to properly cover the leaky case, and the test
now passes.

Also tightened up type checks in runtime.cc and removed Object.observe
functions from knownIssues in fuzz-natives-part2.js.
