Clean up the usage of "MasterPlan" status in ThreadPlans. Only user-initiated plans
should be MasterPlans that want to stay on the plan stack. So make all plans NOT
MasterPlans by default and then have the SB API's and the CommandObjectThread step
commands set this explicitly.

Also added a "clean up" phase to the Thread::ShouldStop so that if plans get stranded
on the stack, we can remove them. This is done by adding an IsPlanStale method to the
thread plans, and if the plan can know that it is no longer relevant, it returns true,
and the plan and its sub-plans will get discarded.

Fix reporting of stop reasons when the StepOver & StepIn plans stop because of a crash or breakpoint. Added the ability for a plan to say it is done but doesn't want to be the reason for the stop.

Rework how master plans declare themselves. Also make "PlanIsBasePlan" not rely only on this being the bottom plan in the stack, but allow the plan to declare itself as such.

Convert the thread plans over from using the stack count to do their logic to using StackID's. This

Thread hardening part 3. Now lldb_private::Thread objects have std::weak_ptr
objects for the backlink to the lldb_private::Process. The issues we were
running into before was someone was holding onto a shared pointer to a
lldb_private::Thread for too long, and the lldb_private::Process parent object
would get destroyed and the lldb_private::Thread had a "Process &m_process"
member which would just treat whatever memory that used to be a Process as a
valid Process. This was mostly happening for lldb_private::StackFrame objects
that had a member like "Thread &m_thread". So this completes the internal
strong/weak changes.

Documented the ExecutionContext and ExecutionContextRef classes so that our
LLDB developers can understand when and where to use ExecutionContext and
ExecutionContextRef objects.

Make the ThreadPlanStepThrough set a backstop breakpoint on the return address from
the function it is being asked to step through, so that even if we get the trampoline
target wrong (for instance) we will still not lose control.

The other fix here is to tighten up the handling of the case where the current plan
doesn't explain the stop, but a plan above us does. In that case, if the plan that
does explain the stop says it is done, we need to clean up the plans below it and
continue on with our processing.

Fixed the LLDB build so that we can have private types, private enums and

Made lldb_private::ArchSpec contain much more than just an architecture. It
now, in addition to cpu type/subtype and architecture flavor, contains:
- byte order (big endian, little endian)
- address size in bytes
- llvm::Triple for true target triple support and for more powerful plug-in

Modified all logging calls to hand out shared pointers to make sure we
don't crash if we disable logging when some code already has a copy of the
logger. Prior to this fix, logs were handed out as pointers and if they were
held onto while a log got disabled, then it could cause a crash. Now all logs
are handed out as shared pointers so this problem shouldn't happen anymore.
We are also using our new shared pointers that put the shared pointer count
and the object into the same allocation for a tad better performance.

Two changes in this checkin. Added a ThreadPlanKind so that I can do some reasoning based on the kind of thread plan
without having to use RTTI.
Removed the ThreadPlanContinue and replaced with a ShouldAutoContinue query that serves the same purpose. Having to push
another plan to assert that if there's no other indication the target should continue when this plan is popped was flakey
and error prone. This method is more stable, and fixed problems we were having with thread specific breakpoints.
