MIPS: Remove kind field from StackHandler.

MIPS: Remove kind field from StackHandler.

Port 15f8213809a57c2a163b500a732c9ffe5160a41a

Original commit message:
This relands commit 96f79568a926966ebcf0685bf9adc947f4e1fbff.

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.
