Use __ARM_ARCH_6ZK__ instead of __ARM_ARCH_6KZ__. The architecture is
technically called ARMv6KZ, but GCC has always called it 6ZK.

Clang defines __ARM_ARCH_6K__ for this target, and is unaffected.

stdout as we crash. Also records the last 3 GCs on the stack so that
it will be part of the minidump.

Moves alignment fill calculations into two static Heap methods.
Adds a Heap method to handle the complex case where filler is potentially needed before and after a heap object.
Makes DoubleAlignForDeserialization explicitly fill after an already
aligned object.

The point of this change is so that when emitting code for a call in
FullCodegen::VisitCall, the statement position is not associated to
any code that loads the function, but to the actual CallIC.

Implements the strong mode proposal's restrictions on changing a strong object's
writable, non-configurable property to non-writable.

Setting the strong bit is still wip, so this change will only affect those
objects that have the bit correctly set. The tests reflect this, and will be
expanded as more objects can be marked as strong.

This introduces a conservative prediction for each exception handler
whether it will locally catch an exception or re-throw it to outside
the code bondaries. It will allow for a more intuitive prediction of
whether an exception is considered "caught" or "uncaught".

We need the shared function info of inlined functions to prevent code
flushing for their unoptimized code, and also to make sure that liveedit
can find the proper functions to deoptimize.

The control flow optimization should work independent of the JSGraph. We
used the JSGraph there because it was convinient, not because it was
necessary.

The SimplifiedOperatorReducer is (mostly) unused, except for the very
rough store elimination, and just eats compilation time.

The list of inlined functions is used in exactly two places - for live
edit and to prevent code flushing for inlined functions - and those are
fine with SharedFunctionInfo and don't require a closure.

This is one additional step towards inlining based on SharedFunctionInfo
instead of JSFunction.
