This patch should fix a test failure in
`Expr/TestIRMemoryMapWindows.test`:
https://lab.llvm.org/buildbot/#/builders/219/builds/6786
The problem here is that since 7991412 landed, all the
`ScriptInterpreter::CreateScripted*Interface` now return a `nullptr`
when using the base `ScriptInterpreter` instance, instead of
`ScriptInterpreterPython` for instance.
This nullptr is actually well handled in the various places where we
create a Scripted Interface, however, because of the way to instanciate
a process, the process plugin manager have to iterate over every process
plugin and call the `CreateInstance` static function that should
instanciate the right object.
So in the ScriptedProcess case, because we are getting a `nullptr` when
trying to create a `ScriptedProcessInterface`, we try to discard the
process object, which calls the Process destructor, which in turns calls
the `ScriptedProcess` plugin `IsAlive` method. That method will fire an
assertion if the scripted interface pointer is not allocated.
This patch address that issue by setting a flag when destroying the
ScriptedProcess object, and checks that flag when calling `IsAlive`.
