85800eff3f Fix issue with getOwnPropertySymbols and hidden properties 
When getting the symbols of an object we need to ignore the hidden
properties of the prototype object since the hidden properties are
represented by a single string key and we will not include that hidden
string in the found names.

819d9f62d0 Fix for 350887: CHECK failure on new_length->IsSmi() 
In ElementsAccessorBase::SetLengthImpl for a dictionary array, we try to
optimize setting array length if the new length is a smi. However, we
refuse to set an array length to less than the index of the highest
non-configurable array element. This index may be outside of smi range.

Handle this case accordingly.

00ba711658 Use a per-isolate cache for the date object JS bits 
The old per-context cache made it difficult for the embedder to notify
v8 of date/time configuration changes. The embedder had to enter all
contexts for the isolate and notify v8 for each context.

With the new per-isolate cache, the embedder only needs to notify v8
once per isolate.

19a04c3a69 A64: Use a scope utility to allocate scratch registers. 
This replaces Tmp0() and Tmp1() with a more flexible scratch register
pool. A scope-based utility can temporarily acquire registers from this
pool as needed.

We no longer have to worry about whether to use Tmp0(), Tmp1() or
something else; the scope can just get the next available scratch
register.

8bd37cb7c3 Refactor script compilation / running & use of helper funcs in test-api.cc. 
The tests were using different kind of constructs for achieving the same
thing. This makes refactoring the compilation API more difficult than it should
be.

cctest.h already contained helpers for compiling and running scripts, but they
were not used consistently.

For example, all these were used for running scripts:

v8::Script::Compile(v8_str("foo"))->Run();
v8::Script::Compile(v8::String::NewFromUtf8(isolate, "foo))->Run();
CompileRun(v8_str("foo"));
CompileRun(v8::String::NewFromUtf8(some_way_to_get_isolate(), "foo"));
v8::Local<v8::Script> script = any_of_the_above; script->Run();

Most of the tests just want to run a script (which is in const char*) and don't
care about how the v8::String is constructed or passed to the compiler API. Using
the helpers makes the test more readable and reduces boilerplate code which is
unrelated to what the test is testing.

1b7055cf54 Unify (Pre)Parser::ParseObjectLiteral and add tests. 
Notes:
- The regexp in the ParseObjectLiteralComment was wrong, made it less wrong (
it's still wrong since trailing commas are not required / allowed).
- Change in logic: In case we have "get somekeyword() { }", the "somekeyword"
was not logged as a symbol by PreParser and not expected in the preparser data
by Parser. This is unnecessary complication; in other contexts where keywords
are allowed as identifiers, they are logged as symbols (see
ParseIdentifierName).

33a46be689 A64: Handle a few TODOs. 
Notes about a few TODOs handled in this patch:

* In ProfileEntryHookStub::Generate:
    Stubs are always called with relocation.

* In CreateArrayDispatchOneArgument:
    The branches to registers can't be conditional. We could use a jump table, but
    there are only 6 different kinds so it is likely not worth it.

* In Builtins::Generate_StringConstructCode:
    Rename the argc register (x0) after its meaning changes.
    Remove a TODO: using a macro would not make the code clearer.

* In Generate_JSEntryTrampolineHelper:
    Remove the TODO and raise an internal issue to investigate this.

* In Disassembler::SubstituteBranchTargetField:
    Print the target address, but we don't have more info on the target.

49cd3d8a65 Allocation tracker: add separate entry for allocations via V8 API 
When object is creating via native V8 API calls JS callstack is empty and the allocation is indistinguishable from say compiler allocations. This change adds a separate entry for such allocations.

Since FunctionInfo not necessarily corresponds to a heap object they are now referred to using their index in the list of all FunctionInfos.

6115a006fd Bugfix for 349874: we incorrectly believe we saw a growing store 
When we set an out of bounds array index, the index might be so large that
it causes the array to go to dictionary mode. It's better to avoid
"learning" that this was a growing store in that case.

This fix also partially reverts a fix for bug 347543, as this fix is
comprehensive and satisfies that repro case as well (partial revert of
v19591).

b9e0b87a5a Clear optimized code cache in shared function info when code gets deoptimized. 
This adds a pointer to the shared function info into deoptimization data of an optimized code. Whenever the code is deoptimized, it clears the cache in the shared function info.

This fixes the problem when the optimized function dies in new space GC before the code is deoptimized due to code dependency and before the optimized code cache is cleared in old space GC (see mjsunit/regress/regress-343609.js).

This partially reverts r19603 because we need to be able to evict specific code from the optimized code cache.

b1ffc7901f A JSArray may have a filler map in the elements pointer. 
We already have code that expects this, but incorrectly asserted that the
filler map case would never happen when allocation folding is turned on.
However, even folding has it's limits, bailing out of continued folding
when the object size grows too large. Therefore, it's a general problem
when verifying JSArray objects, that we might encounter a filler map
in elements().

94af17a845 Fix the bit massaging code in CompleteParserRecorder::WriteNumber. 
The original code, added by
https://codereview.chromium.org/3384003/diff/7001/src/parser.cc 3.5 years ago,
failed to write numbers which contain a chunk of 7 zeroes in the middle. The
smallest such number is 2^14, so this is a problem if the source file to
preparse contains 16384 or more symbols (which happens in the wild).

This bug went unnoticed because the symbol data was not used by Parser (see
https://codereview.chromium.org/172753002/ for starting to use it again) and
there were no tests.

3d85b86e23 Lazy preparsing vs. lazy parsing fix. 
Preparsing is always maximally lazy (every function that can be lazy is preparsed
lazily), but Parser has more complicated laziness logic.

If we're going to parse eagerly, and we have preparse data from lazy preparsing,
we're gonna have a bad time. The symbol stream won't contain symbols inside lazy
functions, and when the Parser parses them eagerly, it will consume symbols from
the symbol stream, and everything will go wrong.

This bug was hidden because the symbol cache was not used for real (see
https://codereview.chromium.org/172753002/ ).

0a01afda76 Re-enable Parser::symbol_cache_ (after a long time!) 
The Parser never used the symbol stream produced by the PreParser for anything
useful, due to a bug introduced 3.5 years ago by
https://codereview.chromium.org/3356010/diff/7001/src/parser.cc.

The bug is that calling Initialize on symbol_cache_ doesn't change its
length. So the length remains 0, and the "if" in Parser::LookupSymbol is always
true, and Parser::LookupCachedSymbol is never called and symbol_cache_ never
filled.

This bug also masked a bug that the symbol stream produced by PreParser doesn't
match what Parser wants to consume. The repro case is the following:

var myo = {if: 4}; print(myo.if);

PreParser doesn't log a symbol for the first "if", but in the corresponding
place, Parser consumes one symbol from the symbol stream. Since the consumed
symbols were never really used, this mismatch went unnoticed.

This CL also fixes that bug.

0d34254f8d Upgrade Symbol implementation to match current ES6 behavior. 
Refresh the implementation of Symbols to catch up with what the
specification now mandates:

* The global Symbol() function manufactures new Symbol values,
  optionally with a string description attached.

* Invoking Symbol() as a constructor will now throw.

* ToString() over Symbol values still throws, and
  Object.prototype.toString() stringifies like before.

* A Symbol value is wrapped in a Symbol object either implicitly if
  it is the receiver, or explicitly done via Object(symbolValue) or
  (new Object(symbolValue).)

* The Symbol.prototype.toString() method no longer throws on Symbol
  wrapper objects (nor Symbol values.) Ditto for Symbol.prototype.valueOf().

* Symbol.prototype.toString() stringifies as "Symbol("<description>"),
  valueOf() returns the wrapper's Symbol value.

* ToPrimitive() over Symbol wrapper objects now throws.

Overall, this provides a stricter separation between Symbol values and
wrapper objects than before, and the explicit fetching out of the
description (nee name) via the "name" property is no longer supported
(by the spec nor the implementation.)

Adjusted existing Symbol test files to fit current, adding some extra
tests for new/changed behavior.

62116e2c12 A64: Let the MacroAssembler resolve branches to distant targets. 
Code generation would fail when assembling a branch to a label that is bound
outside the immediate range of the instruction. A64 is sensitive to this, as the
various branching instructions have different ranges, going down to +-32KB for
TBZ/TBNZ.  The MacroAssembler is augmented to handle branches to targets that
may exceed the immediate range of instructions.

When branching backward to a label exceeding the instruction range, the
MacroAssembler can simply tweak the generated code to use an unconditional
branch with a longer range. For example instead of
    B(cond, &label);
the MacroAssembler can generate:
    b(InvertCondition(cond), &done);
    b(&label);
    bind(&done);

Since the target is not known when the branch is emitted, forward branches uses
a different mechanism. The MacroAssembler keeps track of forward branches to
unbound labels. When the code generation approaches the end of the range of a
branch, a veneer is generated for the branch.

dbce27047e Fixed and improved code for integral division. Fixed and extended tests. 
Arithmetic right shifting is *not* division in two's complement
representation, only in one's complement. So we convert to one's
complement, shift, and go back to two's complement. By permutating the
last steps, one can get efficient branch-free code. This insight comes
from the paleozoic era of computer science, see the paper from 1976:

   Guy Lewis Steele Jr.: "Arithmetic Shifting Considered Harmful"
   ftp://publications.ai.mit.edu/ai-publications/pdf/AIM-378.pdf

This results in better and more correct code than our previous
"neg/shift/neg" dance.

1634631ae4 A64: Tidy up Push and Pop TODOs. 
This addresses several TODOs:
  - Push and Pop requests can be queued up so that arrays of Registers
    can be pushed efficiently, with just one PrepareForPush/Pop.
  - PushMultipleTimes now takes an Operand. This allows variable-length
    arguments arrays to be initialized, for example.
  - A NoUseRealAbortsScope has been added to Abort so that
    AssertStackConsistency can be called from PrepareForPush without
    introducing infinite recursion.

8acefb33fe Test and fix for polymorphic named call deoptimization. 
The fix removes wrong simulates from the number branch of polymorphic
call/field access handling.

The change also fixes the same thing for polymorphic named field
access even thourgh the field access is probably safe in practice
(because it cannot deoptimize). It is better to keep all our simulates
in sync with full codegen.

cd50687b41 (Pre)Parser: Move ParsePrimaryExpression to ParserBase. 
Notes:
- To be able to move the recursive descent functions to ParserBase one at a
time, we temporarily need routing functions from traits to Parser/PreParser,
since the recursive descent functions form a cyclic structure.
- PreParser used to always allow intrinsic syntax. After this CL, it depends on
allow_natives_syntax() which was already in ParserBase.
- This CL also decouples (Pre)ParserTraits better from (Pre)Parser, passing more
information as parameters, so that the Traits don't need to get it from
(Pre)Parser.
