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.

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.

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
appropriate mechanism.

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.

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().

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.

Advance() always checks for stack overflow. If stack indeed overflowed,
current() would hold the kEndMarker. ParseOctalLiteral does not expect
this in the assertion, which causes assertion failure.

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).

Goto does not emit a jump if the target is the next emitted block.
However, if there is an unreachable block between Goto and the jump
target, we still emit a jump even though the unreachable block is
not actually emitted. That jump is unnecessary.
