ea74f0f85a Avoid some unnecessary fast-properties map creations. 
(1) When we have just normalized and re-fastified a map, we don't need to copy it again to set the is_prototype bit.
(2) When defining accessors causes a non-prototype object to go slow, don't force re-fastification.

2b026851ac Scanner: disallow unicode escapes in regexp flags. 
The spec explicitly forbids them. V8 never handled them properly either, just
the Scanner accepted them (it had code to add them literally to the
LiteralBuffer) and later on, Regexp constructor disallowed them.

According to the spec, unicode escapes in regexp flags should be an early error
("It is a Syntax Error if IdentifierPart contains a Unicode escape sequence.").

Note that Scanner is still more relaxed about regexp flags than the
spec. Especially, it accepts any identifier parts (not just a small set of
letters) and doesn't check for duplicates.

5f1ae66d56 Narrow cases where Sparse/Smart versions of Array methods are used 
Added a new %HasComplexElements runtime function (meaning elements that are
non-writable, non-configurable, or have getters and setters) and use it
in UseSparseVariant to filter out cases where the sparse optimizations
can cause V8 to fall out of spec compliance.

Renamed SmartMove/SmartSlice to SparseMove/SparseSlice and guarded them
with the new and improved UseSparseVariant.

These two changes combine let us pass nearly every test in bug-2615.js,
as well as fixing reverse and join on sparse arrays.

Note that there are various test changes in this patch that correct existing
tests to match the correct-by-spec behavior.

This patch depends on https://codereview.chromium.org/666883009, which
better-aligns the behavior of SmartMove with SimpleMove.

8330178b4c The issue is that by handling strings with map/handler pairs instead of a special 
version of the keyed load stub (https://code.google.com/p/v8/source/detail?r=24661),
I allowed polymorphism between string and non-string types in the IC. Before, the
IC would go generic.

Then, at crankshaft time, we special case when we only saw strings. The error
here is that crankshaft can't emit code that handles polymorphism between string
and non-string types. The choice is either to get that to happen (I don't deem
this necessary from a performance point of view, an IC with such type feedback
before would have gone generic), or simply check for the case of "polymorphic
with some string maps" and require crankshaft to go generic. I'll do the latter.

00e90b7e6e Remove deoptimization by patching the call stack. 
We go back to patching the code for lazy deoptimization because ICs need the on-stack return address to read/update the IC address/state.

The change also fixes bunch of tests, mostly by adding more deoptimization points.

(We still need to add code to ensure lazy deopt patching does not overwrite ICs and other lazy deopts; this is coming next.)

aa7198dfdd This CL simplifies var / const by ensuring the behavior is consistent in itself, and with regular JS semantics; between regular var/const and eval-ed var/const. 
Legacy const is changed so that a declaration declares a configurable, but non-writable, slot, and the initializer reconfigures it (when possible) to non-configurable non-writable. This avoids the need for "the hole" as marker value in JSContextExtensionObjects and GlobalObjects. Undefined is used instead.

3d0bf69cd8 Attempt no. 3 to fix Heap::IsHeapIterable and HeapIterator. 
Now we remember new space's top pointer after the last GC to find out if there was a new space allocation since the last GC.

Unfortunately, this not completely safe - the debugger has a callback hook (that can call to JS) at the end of the GC epilogue that can in theory allocate and possibly make the heap non-iterable. We can only hope this does not happen.

dd4c82bbb3 Fix Heap::IsHeapIterable. 
We only consider heap iterable if the new space is empty (in addition to the exisiting old space check).

The change also moves the iterability forcing + allocation prevention gadgets to HeapIterator so that it is impossible to miss them when iterating the heap.
