and sharing it with all of its FuncUnwinders, have each FuncUnwinder
create an AssemblyProfiler on demand as needed. I was worried that
the cost of creating the llvm disassemblers would be high for this
approach but it's not supposed to be an expensive operation, and it
means we don't need to add locks around this section of code.

to its unwind assembly profiler to all of the FuncUnwinders (one
per symbol) under it. If lldb is running multiple targets, you
could get two different FuncUnwinders in the same Module trying
to use the same llvm disassembler simultaneously and that may be
a re-entrancy problem.
Instead, the UnwindTable has the unwind assembly profiler and when
the FuncUnwinders want to use it, they get exclusive access to
the assembly profiler until they're done using it.

debugserver now returns $X09 as the immediate response to
a $k kill process request rather than $W09.
ProcessGDBRemote now properly handles X as indication of
a process exit state.
The @debugserver_test and @lldb_test for $k now properly expects
an X notification (signal-caused exit) after killing a just-attached
inferior that was still in the stopped state.

Rationale:
Pretty simply, the idea is that sometimes type names are way too long and contain way too many details for the average developer to care about. For instance, a plain ol' vector of int might be shown as
std::__1::vector<int, std::__1::allocator<....
rather than the much simpler std::vector<int> form, which is what most developers would actually type in their code
Proposed solution:
Introduce a notion of "display name" and a corresponding API GetDisplayTypeName() to return such a crafted for visual representation type name
Obviously, the display name and the fully qualified (or "true") name are not necessarily the same - that's the whole point
LLDB could choose to pick the "display name" as its one true notion of a type name, and if somebody really needs the fully qualified version of it, let them deal with the problem
Or, LLDB could rename what it currently calls the "type name" to be the "display name", and add new APIs for the fully qualified name, making the display name the default choice
The choice that I am making here is that the type name will keep meaning the same, and people who want a type name suited for display will explicitly ask for one
It is the less risky/disruptive choice - and it should eventually make it fairly obvious when someone is asking for the wrong type
Caveats:
- for now, GetDisplayTypeName() == GetTypeName(), there is no logic to produce customized display type names yet.
- while the fully-qualified type name is still the main key to the kingdom of data formatters, if we start showing custom names to people, those should match formatters

$qC from debugserver now returns the current thread's thread-id (and, like $?, will set a current thread if one is not already selected). Previously it was returning the current process id.
lldb will now query $qProcessInfo to retrieve the process id. The process id is now cached lazily and reset like other cached values. Retrieval of the process id will fall back to the old $qC method for vendor==Apple and os==iOS if the qProcessInfo retrieval fails.
Added a gdb remote protocol-level test to verify that $qProcessInfo reports a valid process id after launching a process, while the process is in the initial stopped state. Verifies the given process id is a currently valid process on host OSes for which we know how to check (MacOSX, Linux, {Free/Net}BSD). Ignores the live process check for OSes where we don't know how to do this. (I saw no portable way to do this in stock Python without pulling in other libs).

data if it is available.
Change ProcessGDBRemote's maximum read/write packet size from a
fixed 512 byte value to asking the remote gdb stub what its maximum
is, using up to 128kbyte sizes if that's allowed, and falling back
to 512 if the remote gdb stub doesn't advertise a max packet size.
Add a new "process plugin packet xfer-size" command that can be used
to override the maximum packet size (although not exceeding any packet
size maximum published by the remote gdb stub).

Currently if you run _any_ python, python has the "lldb.debugger" global variable and it has a strong reference to a lldb_private::Debugger since it is a lldb::SBDebugger object with a shared pointer.
This makes sure that your LLDB command interpreter history is saved each time you quit command line LLDB.

Enable data formatters to see-through pointers/references to typedefs
For instance, if Foo is a typedef to Bar, and there is a formatter for any/all of Bar*, Bar&, Bar&&, then Foo*, Foo&, and Foo&& should pick these up if Foo-specific formatters don't exist

Set the correct FormatManager revision before starting to figure out the new formatters
This can avoid entering some corner cases where as part of figuring out formatters we try to figure out dynamic types, and in turn that causes us to go back in trying to fetch new formatters - it is not only a futile exercise, it's also prone to endless recursion
This would only cause a behavior change if getting this chain started would eventually cause something to run and alter the formatters, a very unlikely if at all possible sequence of events

This fix reduces the stack size of SymbolFileDWARF::ParseType(). It seems that clang is not very good at sharing locations on the stack with local variables in large functions that have many blocks and each variable gets unique locations. The reduction in size was done by:
1 - removing some large locals that were default constructed by not used
2 - Placing some larger local variables into std::unique_ptr<> to make them on the heap
3 - removing local variables there were large and being populated but not being used
4 - reducing the size of some typedefs to llvm::SmallVector<T, N> so that N wasn’t excessively large
