b7caca9f9a When reading the map from a live object, use a barrier load 
It could happen that we shrink a live object on the main thread (e.g.
MigrateFastToSlow) while we're sweeping the same page. The main
thread first creates a filler object that the release-stores the new
map. Therefore it's important to barrier load the map word of live
objects from the sweeper thread.

49baecc42b [turbofan] Mark arm64 cbz/cbnz tbz/tbnz instructions as branch instructions. 
The instruction selector now selects pseudo instructions: CompareAndBranch or
TestAndBranch which are associated with their continuations so that generic
code in the code generator will treat them as branch instruction and will be
able to apply optimization like avoiding branches when the code can falltrhough.

4fa7ae1c07 Optimize Object.seal and Object.preventExtensions 
They both now run fast (due to utilizing transitions instead of always
creating new maps) and sealed or non-extensible objects can stay in
fast mode after transitioning.

This almost entirely reuses the code for transitioning objects
frozen by Object.freeze(), with the added benefit of freeing
up a bit on the map (we no longer keep track of frozen-ness,
as that bit wasn't used for anything interesting).

243764b04b Optimize add/set/delete operations for string keys in Maps and Sets 
This was previously landed in commit 8599f5f, but failed the
collections mjsunit test on ia32 with --deopt-every-n=1. The fixed
patch adds a ClearFlag(HValue::kCanOverflow) call after every
arithmetic operation, which should remove all the deopt points in these
intrinsics.

Ideally, it seems like there should be a way to verify that there are
no deopt points for these inline optimized functions, since there's
nothing to deopt to. But I don't currently know of such a thing.

6680fd1591 Handle invalid parser cache gracefully (move invalid cache handling to embedder). 
Blink already has code for handling invalid cached data. The attached test
ensures that cached data is gracefully rejected if it cannot be used.

This also unifies parser cache and code cache handling.

6230641b83 Optimize testing for an index's existence in packed Arrays 
This patch introduces a new inline runtime function,
%_HasFastPackedElements(), and uses it both in the implementation
of the 'in' operator and in the array builtins to speed
up testing for the existence of an index in an array.

In testing with the microbenchmark on the attached bug,
for example, the runtime goes from 326ms to 66ms.

A reviewer might ask whether the HAS_INDEX macro is worthwhile,
and I tried the same example without it, which pushed the
microbenchmark up to 157ms. So it seems it's worth it to
avoid the function call to IN() if we know we're dealing
with arrays and numbers.

21b23e6966 Move more don't-crankshaft computation to numbering pass 
The "do I inline?" decision needs many of the same inputs as the "should
I even try to crankshaft?" decision.  This change consolidates these
checks in the numbering pass.  It also removes the is_generator() check,
as that's already handled when visiting the initial Yield expression.

881a921bb2 Fix NativesCollection<.>::GetScriptName in natives-external.cc 
As there's no associated bug, here's the issue:
- Some ES6 functionality in Chrome is presently broken; this fixes it.
- The natives (built-in libraries) can be accessed by their 'name'.
  This is used to active ES6 flags.
- Strangely enough, there's an id and a name, where the name is derived
  from the id as "native %s.js", with %s for the id.
- NativesCollection<.>::GetScriptName uses the name.
- NativesCollection<.>::GetIndex uses the id.
- Example:
  NativesCollection<EXPERIMENTAL>::GetIndex("harmony-string") -> 3
  NativesCollection<EXPERIMENTAL>::GetScriptName(3) -> "native harmony-string.js"
- Nobody knows why; it's quite mysterious.
- When introducing the "external startup data", I didn't fully understand this
  and used the id in both places.
- When the "external startup data" was turned on in Chrome, ES6 features broke
  in Chrome since the libraries could no longer be found.
- This CL fixes this and makes the external startup data behave just like the
  built-in version.

93cd816c07 Make TemplateLiteral hashing algorithm more memory efficient 
Previously, a separate string to be hashed (in order to help determine the need to
use a cached Template Call Site) was built up by joining UTF8 spans within a template.

Now, the hash key is generated from the original spans, removing the need to allocate a new
buffer and copy bytes into it.

a03943880c MIPS: harmony-scoping: make assignment to 'const' a late error. 
Port 6ac4de87a8

Original commit message:
Per TC39 Nov 2014 decision.

This patch also changes behavior for "legacy const": assignments to sloppy const in strict mode is now also a type error. This fixes v8:2243 and also brings us in compliance with other engines re assignment to function names (see updated webkit test), but might have bigger implications.
That change can easily be reverted by changing Variable::IsSignallingAssignmentToConst.

9da4998204 Abort optimization in corner case. 
The %OptimizeFunctionOnNextCall sledgehammer can cause a function to be
marked for optimization before it's ever been compiled by fullcode.
This can lead to the situation where a function doesn't have optimization
disabled until we try to compile it optimized.

Basically, the assert should just handle this case more gracefully.

The bug was an error when copying arrays in crankshaft. If it's a holey smi
array, the copy must be done as FAST_HOLEY_ELEMENTS to prevent representation
changes from being inserted that deopt on encountering the hole.

Also, prevent inlining array pop() and shift() if the length is read-only.
