dcac1f144e [wasm] Fixed float-to-int32 conversion to match the spec.
The new implementation detects if the input value is outside i32 range
and traps it that case.

The range check is done as follows:
The input value is converted to int32 and then back to float. If the
result is the same as the truncated input value, then the input value
is within int32 range.

a4e3a3b6a8 [heap] Move to LAB-based allocation for newspace evacuation.
This CL prepare newspace evacuation for parallel execution wrt. to actual
allocations. The priority for allocations is:
* Try to allocate from LAB if objects are below kMaxLabObjectSize
* Allocate directly (synchronized) from newspace for larger objects.
* Fall back to old space allocation (which will be backed by a local compaction
  space in future).

Semantical change: Previously we did fall back to regular new space promotion if
we are OOM in old space. With this CL we fall back to new space promotion, which
could fail because of fragmentation, again leading to an old space allocation
that finally bails into OOM.

Newspace evacuation is still single threaded and requires further changes to
allocation site tracking.

32211800d8 [Interpreter] Generate valid FrameStates in the Bytecode Graph Builder.
Adds FrameState nodes to graphs built by the Bytecode Graph Builder, in
preparation for adding deopt support. Also adds a new
FrameStateType::kInterpretedFunction to allow for specialized deopt
stack translation for interpreted frames. Finally adds support for
disabling typed lowering of binary ops, since the current approach
relies on a FrameState hack which does not apply to interpreted frames

70a7c754bf Implement tracing interface for v8
This is based on the Skia Implementation.

More on the project can be found here:
https://docs.google.com/a/chromium.org/document/d/1_4LAnInOB8tM_DLjptWiszRwa4qwiSsDzMkO4tU-Qes/edit#heading=h.p97rw6yt8o2j

The V8 Tracing platform will replace the isolate->event_logger().
But since the current embedders (namely chromium) currently use the isolate->event_logger, I made the default implementation (event-tracer) call into isolate->event_logger if an event_logger was set.
Once the embedders properly implement the interface (for example in chromium it would look like this: https://codereview.chromium.org/707273005/), the default implementation will be doing nothing.

Once the embedders side is fixed, we will change how V8 uses the tracing framework beyond the call from Logger:CallEventLogger. (which would also include a d8 implementation)

5bd4832492 [es6] Correct Function.prototype.apply, Reflect.construct and Reflect.apply.
Introduce a new Apply builtin that forms a correct and optimizable
foundation for the Function.prototype.apply, Reflect.construct and
Reflect.apply builtins (which properly does the PrepareForTailCall
as required by the ES2015 spec).

The new Apply builtin avoids going to the runtime if it is safe to
just access the backing store elements of the argArray, i.e. if you
pass a JSArray with no holes, or an unmapped, unmodified sloppy or
strict arguments object.

aafc3e5484 [runtime] Drop FIRST/LAST_NONCALLABLE_SPEC_OBJECT instance type range.
The FIRST-LAST_NONCALLABLE_SPEC_OBJECT_TYPE range was accidentially used
in field type tracking, where we should check for JSReceiver instead
(there's no need to exclude JSProxy or JSFunction from tracking).

And the use in %_ClassOf was actually wrong and didn't match the C++
implementation in JSReceiver::class_name() anymore. Now it's consistent
again.

aeb8073c4a Add Isolate::DiscardThreadSpecificMetadata method to embedder API.
If many threads use the same Isolate (or many Isolates) and then
terminate, their PerIsolateThreadData objects are never cleaned
up, resulting in a slow memory leak and, worse, the
PerIsolateThreadData chain getting larger and larger, adversely
affecting performance.

In this situation, embedders will now be encouraged to apply
DiscardThreadSpecificMetadata against any Isolate a thread is
done with, especially if the thread is about to terminate.

Note that it is harmless to run DiscardThreadSpecificMetadata
against an Isolate for which a thread has no thread data and
per-Isolate thread data can be reestablished if a thread starts
using an Isolate again after running DiscardThreadSpecificMetadata
against it.

It is, however, an embedder error to run
DiscardThreadSpecificMetadata against an Isolate in thread with a
Locker for the Isolate in the stack or against an Entered Isolate.

This change cannot cause any change in behavior in existing apps
as the only added coded can only be reached via the new
DiscardThreadSpecificMetadata method.

13412d6693 [wasm] Fixed a problem with float32 stack parameters on 32 bit machines.
The code generation for pushing call parameters on the stack does not
distinguish between float32 and float64 parameters because both are
stored in the same registers. Therefore float32 parameters require two
words on the stack.  The wasm linkage, however, only considered one word
on the stack for float32 parameters, which caused the problem that
float32 parameters were not located correctly on the stack. I fixed the
problem by considering two words for float32 parameters on the stack.

089edbfa97 [debugger] fix debug-evaluate wrt shadowed context var.
Debug-evaluate used to resolve stack variables that shadow
context variables incorrectly, since the stack variable is
not visible in the context chain.

To fix this, we limit local variables accessible by debug-
evaluate to the ones directly referenced inside the function.
What is not referenced by the function itself, is considered
optimized out and not accessible by debug-evaluate.

To achieve this, we duplicate the entire context chain up to
the native context, and write back changes after debug-
evaluate. Changes to the original context chain will however
be overwritten. This already happens for catch and block
scopes though.

Also fix a crash caused by declaring variables inside debug-
evaluate.

5c3bfe8f57 During property reconfiguring ensure that the first map that gets new descriptors is the one that owns the whole descriptor array.
This is necessary to guarantee that the whole descriptor would be marked, otherwise DescriptorArray pretenuring would cause crashes.

d83057b4ce [wasm] Change the return type of traps for tests, and added ftoi64 instructions.
Before this change traps always returned a 32 bit word in tests. With this
change traps return either a 32 bit word or a64 bit word, depending on the size
of the actual return value of the test.

Additionally this CL implements the wasm instructions I64SCONVERTF32,
I64UCONVERTF32, I64SCONVERTF64, and I64UCONVERTF64.

97161a29ed [turbofan] Change TruncateFloat32ToUint64 to TryTruncateFloat32ToUint64.
TryTruncateFloat32ToUint64 converts a float32 to a uint64. Additionally it
provides an optional second return value which indicates whether the conversion
succeeded (i.e. float32 value was within uint64 range) or not.

I implemented the new operator on x64, arm64, and mips64. @v8-ppc-ports, can you
please take care of the ppc64 implementation of the second output?

Additionally I fixed a bug on x64 and mips64 in the implementation of
TryTruncateFloat64ToUint64. Cases where the input value was between -1 and 0
were handled incorrectly.

4c5b3609fd Initial import of v8-native WASM.
As discussed in person, this adds the code from v8-native-prototype into
V8 proper, guarded by GYP flags that do not build the code by default.
Passing wasm=on to 'make' or setting v8_wasm as a GYP flag activates
building of this code.

An additional header file is added to and exported from the compiler
directory, src/compiler/wasm-compiler.h. This exposes a limited interface
with opaque Node and Graph types to the decoder to build TF graphs, as
well as functions to compile WASM graphs.

The mjsunit tests added are blacklisted because they fail without the
WASM object exposed to JS, which is also disabled by the build config
option.

This corresponds closely to 5981e06ebc, with some formatting fixes and moving some files into src/compiler.

- MachineSemantic

Both enums are usable on their own, and this change switches some places from using MachineType to use just MachineRepresentation. Most notably:
- register allocator now uses just the representation.

95844d94f3 [turbofan] Changed TruncateFloat64ToInt64 to TryTruncateFloat64ToInt64.
The new operator provides a second output which indicates whether the
conversion from float64 to int64 was successful or not. The second
output returns 0 if the conversion fails. If the conversion succeeds,
then the second output is differs from 0.

The second output can be ignored, which means that the operator can be
used the same way as the original operator.

I implemented the new operator on x64 and arm64. @v8-mips-ports and
@v8-ppc-ports, can you please take care of the mips64 and ppc64
implementation of the second output?

b634a61d84 [es6] implement destructuring assignment
Attempt #<really big number>

Parses, and lazily rewrites Destructuring Assignment expressions. The rewriting strategy involves inserting a placeholder RewritableAssignmentExpression into the AST, whose content expression can be completely rewritten at a later time.

Lazy rewriting ensures that errors do not occur due to eagerly rewriting nodes which form part of a binding pattern, thus breaking the meaning of the pattern --- or by eagerly rewriting ambiguous constructs that are not immediately known

e89e08ca14 Revert of Provide call counts for constructor calls, surface them as a vector IC. (patchset #4 id:60001 of https://codereview.chromium.org/1476413003/ )
Reason for revert:
Seems to be (mostly) responsible for the most recent Speedometer regression, not 100% sure. Let's see what the bots have to say.

Original issue's description:
> Provide call counts for constructor calls, surface them as a vector IC.
>
> CallIC and CallConstructStub look so alike, at least in the feedback they gather even if the implementation differs...and CallIC has such a nice way of surfacing the feedback (CallICNexus), that there is a request to make CallConstructStub look analogous. Enter ConstructICStub.

1e4681c33f Preserve information about dots in numbers across parser rewriting.
Fix several operations in the parser that rewrite constant expressions
to preserve knowledge regarding whether a value originally contained a ".".
This information is required to accurately validate Asm.js typing.

Making the assumption that if either side of a binary operation contains
a dot, that the rewritten expression should be treated as a double for
Asm.js purposes. This is a slight deviation from the spec (which
would forbid mix type operations).

282e9411f2 [turbofan, arm64] Fix native stack parameters on arm64.
I added a flag to the CallDescriptor which indicates that the native
stack should be used for a CallObject instead of the js stack on arm64.

Additionally I removed the use of EmitPrepareArguments because the
current implementation does not work when float and int parameters are
mixed. I plan to fix it in a future CL, because currently I have a
problem figuring out the type of a parameter.
