Handling expression decomposition and array bounds check hoisting: working code with lots of debugging PrintFs, postdominance check still missing.

When spilling live range with not register uses inside the loop try to move spilling out of the loop.

This allows to minimize amount of memory moves on the back edge.

Bottom-up view of CPU profile can be restored based on top-down profile data. So there is no need to spend resources on creating both of them inside V8.

I tried to limit the use of v8::Isolate::GetCurrent() and v8::internal::Isolate::Current() as much as possible, but sometimes this would have involved restructuring tests quite a bit, which is better left for a separate CL.

After r13912, we saw a small regression in Kraken crypto-aes and
crypto-ccm on Nexus 4. This patch, proposed by Rodolph Perfetta,
addresses that without regressing other platforms.

Instead of looking at the exponent of double_input and trying to figure
out if the conversion will overflow, eagerly do the VCVT and return
early unless it saturated.

Minor cleanups on the way, e.g. making sure that we never use something after an allocation failed. Style question: Should we switch to some kind of MUST_USE_RESULT-style to ensure that we handle failures consistently? Not sure...

Prevously v8 put a link to each context variable into a function where
the variable is visible.
Because of that if there are N functions sharing a context having M variables
then N*M links were created for the snapshot.
The fix makes v8 to put the links into the context object.
