c3c185c173 Make invalid LHSs a parse-time (reference) error 
This is required by the spec. It also prevents crashes resulting from the attempt to read type feedback for the RHS of an invalid assignment which full codegen never actually allocated info for.

To do: check properly in preparser already.

dd28969c1c Continued fix for 351257. Reusing the feedback vector is too complex. 
Attempting to re-use the type feedback vector stored in the
SharedFunctionInfo turns out to be difficult among the various cases.
It will be much easier to do this when deferred type feedback processing
is removed, as is in the works.

Created bug v8:3212 to track re-introducing the optimization of reusing
the type vector on recompile before optimization.

The CL also brings back the type vector on the SharedFunctionInfo.

713aa33f2a Fix of argument materialization of captured heap numbers. 
The escape analysis calculates the number of slots in an object as
no-of-slots = object-size / pointer-size.  This gives 3 slots for
heap numbers on 32-bit architectures (one slot for the map, two for
the double value); however, my argument materialization code assumed
just two slots (map + value). Since Hydrogen allocates heap numbers
quite rarely, it is hard to produce a more meaningful repro than the
one provided by Clusterfuzz. Any suggestions are welcome.

The fix is simple - we just read out all extra slots (beyond the map
and the double) for heap numbers.

7477bc39ca 350884: KeyedStoreIC miss didn't handle a transitioning case. 
It's possible to get a transitioned map with no links to the origin
map if it's a shared map. Code in KeyedStoreIC::StoreElementStub
assumes it can check if two maps are in the same family by
traversing the transition array. Long term, the "family" relationship
should be recognized with the Normalized Map Cache. For now, allow
the IC to remain monomorphic in this case if the receiver map and
the previous receiver map are the same.

Filed V8 issue 3210 (https://code.google.com/p/v8/issues/detail?id=3210)
to track the issue with the Normalized Map Cache.

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().
