5a54b7030d ARM: Don't emit a write barrier for an inlined keyed load

9added5953 Clear function breakpoints in Debug::HandleWeakDebugInfo callback. 
When removing debug_info from SharedFunctionInfo, clear all breakpoints associated with that debug_info.
This is needed because function will live in heap until next gc, and therefore can be found
by Runtime::FindSharedFunctionInfoInScript.

97ecc50377 ARM: Correctness fix to Math.pow optimization 
The change in r4990 contained a bug in Math.pow when then exponent was a large negative smi. In that case calculating 1/Math.pow(x,-y) did not provide the correct result as Math.pow(x,-y) would overflow ti infinity. This was caught by Sputnik test S8.5_A13_T1.

6044b33766 Implement IC for storing to dictionary case objects. 
The IC stub is completely generic, so there will only be one such stub
in the system.

Added a new overloaded version of the macro assembler RecordWrite
method for cases where we have the address we store to computed up
front.

4ad3fdb1f4 Update the ES5 conformance tests to the latest version and fix test 
expectations.

We are currently using a rather old version of the ES5 conformance
tests and there has been a range of bug fixes in the test set. This
change brings us up to date. 

In addition, our current test expectations discards the all chapters
but chapter 15. I have enabled the other chapters, cleaned up the
tests that we no longer fail on, and filed bugs for tests that we fail on.

It seems some of the bugs on the es5 conformance bug-tracker has been
fixed but not marked fixed. I will file bugs for the newly discovered
test bugs.

8ab6832203 Add "has fast elements" bit to maps and use it in inlined keyed loads. 
A potential issue with this change is creating lots of maps when
objects flip between fast/slow elements modes.  We could add special
transitions to avoid this.  Yet testing this on our benchmarks, gmail,
and wave seems to indicate that this is not a real problem.

ae39e059c2 Take survival rates of young objects into account when choosing old generation limits. 
Stable high survival rates of young objects both during partial and
full collection indicate that mutator is either building or modifying
a structure with a long lifetime.

In this case we aggressively raise old generation memory limits to
postpone subsequent mark-sweep collection and trade memory space
for the mutation speed.
