Jim Ingham 923886ce2c Don't try to use "OkayToDiscard" to mean BOTH this plan is a user plan or not AND unwind on error.

Greg Clayton 1ac04c3088 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.

Jim Ingham ef65160016 Improve the x86_64 return value decoder to handle most structure returns.
Switch from GetReturnValue, which was hardly ever used, to GetReturnValueObject
which is much more convenient.
Return the "return value object" as a persistent variable if requested.

Jim Ingham ce553d885a Enhanced the ObjC DynamicCheckerFunction to test for "object responds to selector" as well as
"object borked"...  Also made the error when the checker fails reflect this fact rather than
report a crash at 0x0.

Also a little cleanup:
- StopInfoMachException had a redundant copy of the description string.
- ThreadPlanCallFunction had a redundant copy of the thread, and had a 
copy of the process that it didn't really need.

Sean Callanan 1782783095 Added support for generating expressions that have
access to the members of the Objective-C self object.

The approach we take is to generate the method as a
@category on top of the self object, and to pass the
"self" pointer to it.  (_cmd is currently NULL.)

Most changes are in ClangExpressionDeclMap, but the
change that adds support to the ABIs to pass _cmd
touches a fair amount of code.

Jim Ingham f48169bb4f Moved the code in ClangUserExpression that set up & ran the thread plan with timeouts, and restarting with all threads into a utility function in Process. This required a bunch of renaming.
Added a ThreadPlanCallUserExpression that differs from ThreadPlanCallFunction in that it holds onto a shared pointer to its ClangUserExpression so that can't go away before the thread plan is done using it.

Fixed the stop message when you hit a breakpoint while running a user expression so it is more obvious what has happened.
