fb5dc79983 MIPS: Remove kind field from StackHandler.
Port 15f8213809

Original commit message:
This relands commit 96f79568a9.

This makes the Isolate::Throw logic not depend on a prediction of
whether an exception is caught or uncaught. Such a prediction is
inherently undecidable because a finally block can decide between
consuming or re-throwing an exception depending on arbitray control
flow.

There still is a conservative prediction mechanism in place that
components like the debugger or tracing can use for reporting.

With this change we can get rid of the StackHandler::kind field, a
pre-requisite to do table-based lookups of exception handlers.

0e024449b8 Make counter and histogram related callbacks part of the Isolate::CreateParams.
Some native counters (e.g. KeyedLoadGenericSlow) are referenced from stubs that are generated very early in the Isolate lifecycle before v8::Isolate::New returns. Thus counter lookup callback also needs to be installed early prior to v8::internal::Isolate::Init call. Otherwise assembler will just assume that the counter is not enabled and produce no code from IncrementCounter - because address of the counter is not yet available.

Histogram related callbacks are moved for consistency to make them able to collect samples which occur at isolate initialization time.

8685219066 PPC: Changes to allow AIX to compile with gcc 4.8.3
We were able to remove most of our changes needed to compile
on AIX with an earlier compiler level.  These changes are the
remaining ones.

The changes in heap/heap.cc are needed because otherwise the
compiler complains that result is potentially used before
it is initialized.

The changes in heap/mark-compact.cc are required because
AIX supports the full 64 bit address range so the check
being guarded is invalid.

The changes in build/toolchain.gypi and
test/cctest/cctest/gyp are aix only and are adjust the
compile/link options to allow the AIX build to succeed.

Each leaf for an inlined function will have a list of deopts and their pc offsets.
So when deopt happens I'll be able to map the deopt pc_offset into
inlined function id and point the web developer to the exact place
where deopt has happened even if it was in the inlined function.
