Make CTX allocatable by the register allocator.
...
This change makes CTX available by not caching the current
context while in Dart code. Instead the current context
is held in a local variable (:saved_current_context_var) and
is passed as argument in CTX at calls.
This also simplifies a lot of code in the debugger: As a result,
Isolate::top_context is not needed anymore since the current context
can always be extracted from a Dart frame.

Do not notify debugger on stack overflow

Don’t call back to the debugger on out of memory and stack overflow
exceptions. The debugger can’t do anything meaningful on the VM
when the stack is full.
This should eliminate crashes we see in Dartium devtools.
This means we can no longer intercept stack overflows with the debugger.
In a later change, I plan to add uncomment the code that notifies
the debugger of the exception after the stack in unwound. Before this
notification gets uncommented, we need to make sure that debuggers
can handle notifications with an empty stack.

Fixes bug where we would occasionally materialize a corrupted object.
...
On the slow path for a stack overflow check we manually spill the live
registers before our call to the runtime function. We were updating
all uses of these spilled registers in the Environment object but this
was not enough - we also need to update any uses of these spilled
registers in MaterializeObjectInstrs which are hanging off of the
Environment.
This would fail when a deoptimization was triggered during a stack
overflow check and a materialized object happened to refer to
registers.
I've been chasing this for a while and I was able to get it to
reliably reproduce by using the --stacktrace_every=N and the
--stacktrace_filter flags, which were added for this purpose.
ALSO:
Set the top context to null on exceptions/errors. This is needed for
the --verify-incoming-context flag.

Fix for issue 11680
...
- implicitly store a full stack trace in Error objects when they are thrown.
- the shlFromInt on Mints and Bigints was trying to allocate a new OutOfMemory
exception objects instead of using the pre-allocated exception object.
Made the implementation of these methods native so that they can use the
pre-allocated object.
- Ensure that it is not possible to allocate new OutOfMemory or StackOverflow
exception objects.
