FastNewClosureStub failed to load the cached literals array.

Also, less efficient code was generated because of negative keyed load
offsets. I changed this to benefit from HLoadKeyed dehoisting.

Parser: fix confusion when there are multiple errors to report.

(For more details, see bug.)

The problem occurs when a parsing function hits a stack overflow, but still
manages to return something meaningful. This happens because the call to
ParserBase::Next() which hits the stack overflow will still return a valid token
(the last token which we had already read), and only the next call after the
stack overflow will return INVALID. So for example ParseIdentifier will still
return a valid identifier even if we've hit a stack overflow.

In this case, some upper recursion level might detect and report a valid syntax
error, and then we bail out of the recursive descent because of the syntax
error. So we end up having both stack overflow and a syntax error present. When
we try to report the stack overflow after parsing (e.g., end of ParseLazy), the
isolate already has the syntax error as a pending exception, and a CHECK fails.

This fix suppresses the syntax errors in when a stack overflow has been
detected.

Differentate between code target pointers and heap pointers in constant pools.

Separate out code target pointers from normal heap pointer entries in constant
pool arrays so that the GC can correctly relocate these pointers using the

Special case the recording of constant pool entries in the slot buffer.

This CL enables RelocInfo pointers which live in the constant pool to be treated
as normal pointers by the slot buffer, avoiding the requirement of creating fake
RelocInfo objects during UpdateSlots() in order to update these slots. This
is possible because constant pool entries are just pointers and don't require
the RelocInfo machinary to be updated.

EmbeddedObject constant pool entries can be added untyped to the slot buffer,
while code targets are still typed in order to correctly update the target
address based on the relocated code object.

Note: this is required in order to enable OOL constant pool support on Arm, but
should be benifitial for the current inline constant pool used by Arm code.

Deal with filler object map pointers in the ool constant pool correctly.

This CL updates
StoreBuffer::FindPointersToNewSpaceOnPage such that it skips constant pool array objects. Constant Pool Arrays should never have pointers to the new space and might contain pointers to the FreeSpace map (e.g., due to code
being generated which needs to do a map-check on a FreeSpace object) which would incorrectly treated as a filler object if processed by FindPointersToNewSpaceOnPage().

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.

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).

MIPS: Consistenly handle power-of-2 divisors in division-like operations.

Port r19715 (0d6d244)

Original commit message:
Lithium currently supports 3 division-like operations on integral
operands: "Normal" division (rounding towards zero), flooring division
(rounding towards -Infinity) and modulus calculation (the counterpart
for the "normal" division). For divisors which are a power of 2, one can
efficiently use some bit fiddling to avoid the actual division for such
operations. This CL cleanly splits off these operations into separate
Lithium instructions, making the code much more maintainable and more
consistent across platforms.

There are 2 basic variations of these bit fiddling algorithms: One
involving branches and a seemingly more clever one without branches.
Choosing between the two is not as easy as it seems: Benchmarks (and
probably real-world) programs seem to favor positive dividends,
registers and shifting units are sometimes scarce resources, and branch
prediction is quite good in modern processors. Therefore only the
"normal" division by a power of 2 is implemented in a branch-free
manner, this seems to be the best approach in practice. If this turns
out to be wrong, we can easily and locally change this.
