“process attach” should ask the same questions as process launch if there is a current process.
“process connect” then “process launch” or “process attach” should actually work.

PC relative loads are missing disassembly comments when disassembled in a live process.
This issue was because some sections, like __TEXT and __DATA in libobjc.A.dylib, were being moved when they were put into the dyld shared cache. This could also affect any other system that slides sections individually.
The solution is to keep track of wether the bytes we will disassemble are from an executable file (file address), or from a live process (load address). We now do the right thing based off of this input in all cases.

Partial fix for the above radar.
Call ThreadList::Clear() in the ThreadList destructor so if any other threads currently have the thread list mutex, we won't destroy the list for them while they are using it. ThreadList::Clear() takes the mutex and clears the thread list contents.

- Includes a stub for AVX support in the x86-64 register context and a failing test for register sets that are unavailable.
Thanks to Greg Clayton for his review feedback.

- All Linux logging channels now use a single global instance of lldb_private::Log, to handle the case of logging during process tear down.
- Also removed a single use of LogSP in FreeBSD and fixed a typo in a comment while reading through ProcessKDPLog.

Holding the Python lock while we call the Python C API to post-process objects returned from the OS plugins
This should avoid issues where some Python objects get invalidated while we are in the middle of processing them and we end up with an invalid Python state and a crash

LLDB is crashing when logging is enabled from lldb-perf-clang. This has to do with the global destructor chain as the process and its threads are being torn down.
All logging channels now make one and only one instance that is kept in a global pointer which is never freed. This guarantees that logging can correctly continue as the process tears itself down.

With this notion, if parties outside the ScriptInterpreter itself need to acquire a lock on script APIs, they can do so by a pattern like this:
{
auto lock = interpeter->AcquireInterpreterLock();
// do whatever you need to do...
} // lock will automatically be released here
This might be useful for classes that use the Python convenience objects (e.g. PythonDictionary) to ensure they keep the underlying interpreter in a safe and controlled condition while they call through the C API functions
Of course, the ScriptInterpreter still manages its internal locking correctly when necessary :-)

The algorithm to access an item in a __NSArrayM was not reacting properly to deletions
The fix is to use a smarter formula that accounts for items shifting and the resulting notion of offsets in the table

- Making an error message more consistent
- Ensuring the element size is not zero before using it in a modulus
- Properly using target settings to cap the std::list element count
- Removing spurious element size calculations that were unused
- Removing spurious capping in std::map

ValueObjects themselves use DumpValueObjectOptions as the currency for the same purpose
The code to convert between these two units was replicated (to varying degrees of correctness) in several spots in the code
This checkin provides one and only one (and hopefully correct :-) entry point for this conversion
