f8738e6d74 Cleanup scanner character streams. 
- GenericStringUtf16CharacterStream::start_position_ was unused.
- GenericStringUtf16CharacterStream inherits from BufferedUtf16CharacterStream,
so no need to initialize buffer_cursor_ and buffer_end_ twice (this makes it
clearer which class in the inheritance chain takes care of which variables).

The Isolate* member of ParserBase::FunctionState was only used by
Parser. Removing it makes it clear that there are no isolates in
PreParser. (There's also no Zone, since PreParserTraits::Type::Zone is void.)

The deopt will not happen in production code, since we check that
lengths of fixed typed arrays are smis before calling
TypedArrayInitialze, but that makes deopt bot happy.

4608bdeccc With this fix, we only create the enum cache for own property descriptors (originally we cached all descriptors in the map). The problem was that the size of all descriptors could be trimmed during GC triggered by allocating the storage for the cache, so we could have ended up with a wrong storage size. 
This is really Toon's fix, I have only created a small repro case.

Port r20252 (d0f806b)

Original commit message:
This splits all runtime function into 3 categories:
1) RUNTIME: implemented in runtime and called from both full and optimized code.
2) RUNTIME_HIDDEN: implemented in runtime, never called directly from JS builtins.
3) INLINE: inlined in both full and optimized code
4) INLINE_OPTIMIZED: inlined in optimized code, implemented in runtime for full code.

25260c2b9a PreParser cleanup: no need to track with-ness of scopes. 
Historically, we used to track the "with-ness" of a scope differently; not
creating a with scope, but setting a property on the scope (see
https://codereview.chromium.org/5166006 ). For laziness decisions, checking the
with-ness should be unnecessary: the current scope is function scope, and if the
outer scope is global scope, there's surely no with scope in between.

586f64e1f3 Revert "Use constant length for memcpy on A64 simulator." 
This reverts commit r20141 which broke the build with some GCC versions. The
reason behind that is GCC emits a warning about code which can never be reached,
but GCC can't figure that out.

The right approach would be using template specialization instead of these
runtime if/then/else cascades, which would be nicer from a SW engineering
perspective, too.

e9358fa9ce Increase the "local variables in a function" limit. 
The limit was originally added to avoid having large user-controlled constants
(variable indexes) in the code generated by full-codegen.

History behind this change:

The original CL for adding the limit was https://codereview.chromium.org/7003030
and at that time, the limit was 32767.

Reason for adding the limit (in CL comments): "The motivation behind this change
is to avoid large user controlled constants in the code. The slot_operand used
in the IA32 full code generator uses a relative load where the local index is an
(negative) immediate."

The limit was then bumped to 65535 by https://codereview.chromium.org/10965063
and to 131071 by https://codereview.chromium.org/11099063.

a03e80c3a5 MIPS: Pretenure call new support. 
Port r20076 (b7b1372)

Original commit message:
When FLAG_pretenure_call_new is on, we emit mementos on new object creation
in full code, and consume the feedback in crankshaft. A key difference in the
generated code for stubs is the allocation of an additional type vector slot for the
CallNew AST node, which simplifies the CallConstructStub and CallFunctionStub
considerably.

Some performance tuning still needs to be addressed, therefore the flag is off at
this moment, though fully functional. The goal is to remove the flag as soon as
possible, which allows much code deletion (yay).

0acbcf9876 Reland "Add out-of-line constant pool support to Arm." 
This CL adds out-of-line constant pool support to Arm.  A ConstantPoolBuilder
object is introduced to manage building of the ConstantPoolArray for a given
code object.

This CL depends on the following CLs landing first:

611ea747ef A64: Handle a few TODOs. 
Below are notes about some of the TODOs handled.

* In Simulator::Debug:
    We haven't had issues with printing in the debugger for a while. If the
    feature turns out to be still lacking an issue can be raised.

* In SubStringStub::Generate:
    There is no need to jump there. The StringCharAtGenerator is asked to set
    the result in x0, and the return sequence following only uses two instructions.
    Also, we would need to jump after the native counter increment instead of the
    return_x0 label.

* In ArrayPushStub::Generate:
    Raised an internal issue to check and update the ARM code.

* In MacroAssembler::CopyBytes:
    The new code should be faster for bulk copies. Raised an internal issue to
    investigate and improve this function.

* In MacroAssembler::EnterExitFrame:
    Unless we actually find something is wrong, this is working and looks ok.
    Also fixed the comments about the FP registers.

* Comment for BumpSystemStackPointer:
    Removed the comment at the declaration site and updated the TODO in the
    implementation.
