53eb53f4af CPUProfiler: It is not clear why we are using Handle<Object> for scriptId. Lets flip it into Smi/int. 
By the nature it is integer. So we can work with it as with Smi internaly and use int in the external API.

66efb96621 Fix compilation error introduced with r15287. 
REGEXP was added to Code::Kind after TO_BOOLEAN_IC, but NUMBER_OF_KINDS,
which is used as array size for table[] in ReportCodeKindStatistics, was
still TO_BOOLEAN_IC + 1 (indirectly via LAST_IC_KIND).

a527f451bc Deprecate old code aging mechanism. 
The old code aging mechanism is too agressive with flushing as it leads
to many functions being flushed and recompiled over and over again. By
now the new code aging mechanism has stabilized enough to deprecate the
old fallback mechanism.

36e91242fd Make Object.freeze fast 
This patch both speeds up the freeze operation itself, but also
allows properties to remain in fast mode. Objects with non-empty
elements backing stores still end up with slow elements.

Relanding r14758 and r14759 with fix for Test262: only mark properties
and elements READ_ONLY if they are not JS setter/getters. Tightened up
tests to assert frozen-ness, and added targeted tests for the new code
(covering accessors).

71dc9e165f Capture receiver in generator object 
Previously there has been no reason to context-allocate the receiver, so
access to the receiver always goes through the stack.  This was failing
with generators, which assumed that forcing context allocation would
relieve the need of storing anything but the context and the function on
the stack.

This CL adds a slot in generator objects to capture the receiver, and
restores it when resuming a generator.
