94ad3b1826 Refactor script position calculation
Script position calculation logic (i.e. line & column numbers for a
given code position) is now based on a single method
Script::GetPositionInfo(). Refactored related code in isolate.cc and
js/messages.js to use the new method. The line_ends accessor is still
in use by chromium and thus cannot be removed yet.

e43fbde72b [Interpreter] Preserve source positions in peephole optimizer.
The original peephole optimizer logic in the BytecodeArrayBuilder did
not respect source positions as it was written before there were
bytecode source positions. This led to some minor differences to
FCG and was problematic when combined with pending bytecode
optimizations. This change makes the new peephole optimizer fully
respect source positions.

b2d8bfc793 [heap] Fine-grained JSArrayBuffer tracking
Track based on JSArrayBuffer addresses instead of the attached backing store.
This way we can later on iterate buffers on a single page. The reland also
switches to a page-based implementation where a page contains the set of its
contained (live and dead) buffers.

Details of tracking:
- Scavenge: New space pages are processes in bulk on the main thread
- MC: Unswept pages are processed in bulk in parallel. All other pages
  are processed by the sweeper concurrently.

cc71837fda [builtins] Migrate String.fromCharCode to C++.
The previous JavaScript version created way too many ConsStrings for
longer strings, i.e. when using String.fromCharCode together with
Function.prototype.apply and arrays of char codes.

This version now always allocates sequential strings and therefore uses
way less memory when turning longer character sequences into strings,
and therefore fixes the memory regression on Google Maps.

cbdb373804 [turbofan] Add FixedArray peephole optimizations to CodeStubAssembler
Previously, CodeStubAssembler macros performing FixedArray element accesses had
to compute offsets to elements explicitly with a fair amount of duplicated
code. Furthermore, any peephole optimizations that could produce better code--
like recognizing constant indices or combining array index computation with Smi
untagging--were also duplicated.

This change factors the code to compute FixedArray index offsets into a common
routine in the CodeStubAssembler that applies standard peephole optimizations to
all accesses. In order to do this, it also introduces limited introspection into
the up-until-now opaque Node* type exported from code-assembler.h, allowing
Nodes to be queried whether they are constant and extracting their constant
value in that case.

f241a61a34 [Interpreter] Support compiling for baseline on return from interpreted function.
We cannot tier up from interpreted to baseline code when there is an
activation of the function on the stack. This significantly regresses
the performance of recursive functions since they are unlikely to get
tiered up.

This CL adds the ability for a function to be marked for baseline
compilation when it returns. To do this we patch the
InterpreterEntryTrampoline return address to point to
InterpreterMarkBaselineOnReturn, which leaves the
interpreted frame and recompile the function for
baseline.

This improves the score of EarlyBoyer by ~8x for Ignition.

Also, would be nice if the test output could be a bit shorter and only print what's necessary to trace a failure. Or split things into more smaller tests. Like that, these logs must be processed, json-encoded/decoded and sent around through the infrastructure.

Some chars in the output make the json encoder unhappy, therefore the infrastructure can't nicely display the failures.

d0c65f93bf [parser] Relex restriction on reserved words
Some IdentifierNames are only included in the set of FutureReservedWords
for strict mode code. Outside of strict mode, these IdentifierNames may
be used as Identifiers. Notably, this includes their use as
BindingIdentifiers in LexicalBindings.

From ES2015 12.1.1 Static Semantics: Early Errors (Identifiers):

> It is a Syntax Error if this phrase is contained in strict mode code
> and the StringValue of IdentifierName is: "implements", "interface",
> "let", "package", "private", "protected", "public", "static", or
> "yield".

http://www.ecma-international.org/ecma-262/6.0/#sec-identifiers-static-semantics-early-errors

Due to a error in its heuristic for disambiguating the `let` token, V8
does not currently allow any of the strict-mode-only FutureReservedWords
to be used as a BindingIdentifier outside of strict mode.

Update V8's heuristic for disambiguating the `let` keyword to account
for strict mode, enabling these IdentifierNames to be used

8352ad50e6 [Interpreter] Change LogicalNot to ToBooleanLogicalNot and add non-ToBoolean version.
Makes LogicalNot bytecode not do the ToBoolean operation, and add support in the
peephole optimizer to choose between the appropriate bytecode depending upon
whether the previous bytecode emitted a boolean or not.

2123afff52 Remove more unused bailout reasons.
There's a script for finding them (tools/check-unused-bailouts.sh), but make
sure you don't have an old .bailout-reason.h.swp or such around when using it...

551e0aa11b [es6] Reintroduce the instanceof operator in the backends.
This adds back the instanceof operator support in the backends and
introduces a @@hasInstance protector cell on the isolate that guards the
fast path for the InstanceOfStub. This way we recover the ~10%
regression on Octane EarleyBoyer in Crankshaft and greatly improve
TurboFan and Ignition performance of instanceof.

Since we are going to move Sampler as library, we creates tick-sample.[h|cc] for
TickSample, in order to maintain legacy code.

d33aedb7b9 Revert "Fix TypedArray Property optimizations", add regression test and eliminate dead code
This reverts commit 41d571dfe8.

Reason for revert: This patch breaks the correctness of the typedarray
properties such as length, byteOffset, byteLength.

The accessor check optimization code is dead code eliminated. A follow
up patch will fix this optimization correctly.

This is a first step to removing the support for the OldFunctions
section altogether, which will greatly simplify the encoder and remove
the need to do local variable remapping in asm->wasm.
