Jim Ingham 41f2b940c9 Fixed a few places where we were doing:
uint32_t size = ThreadList.GetSize();
for (i=0; i < size; ++i)

without grabbing the thread list mutex.

Dmitri Gribenko 7acbf00f96 Comment AST: TableGen'ize all command lists in CommentCommandTraits.cpp.
Now we have a list of all commands.  This is a good thing in itself, but it
also enables us to easily implement typo correction for command names.

With this change we have objects that contain information about each command,
so it makes sense to resolve command name just once during lexing (currently we
store command names as strings and do a linear search every time some property
value is needed).  Thus comment token and AST nodes were changed to contain a
command ID -- index into a tables of builtin and registered commands.  Unknown
commands are registered during parsing and thus are also uniformly assigned an
ID.  Using an ID instead of a StringRef is also a nice memory optimization
since ID is a small integer that fits into a common bitfield in Comment class.

This change implies that to get any information about a command (even a command
name) we need a CommandTraits object to resolve the command ID to CommandInfo*.
Currently a fresh temporary CommandTraits object is created whenever it is
needed since it does not have any state.  But with this change it has state --
new commands can be registered, so a CommandTraits object was added to
ASTContext.

Also, in libclang CXComment has to be expanded to include a CXTranslationUnit
so that all functions working on comment AST nodes can get a CommandTraits
object.  This breaks binary compatibility of CXComment APIs.

Now clang_FullComment_getAsXML(CXTranslationUnit TU, CXComment CXC) doesn't
need TU parameter anymore, so it was removed.  This is a source-incompatible
change for this C API.

DeLesley Hutchins 5ff1644e62 Thread-safety analysis: differentiate between two forms of analysis; a precise
analysis that may give false positives because it is confused by aliasing, and
a less precise analysis that has fewer false positives, but may have false
negatives.  The more precise warnings are enabled by -Wthread-safety-precise.
An additional note clarify the warnings in the precise case.

Jakob Stoklund Olesen 8b9dce5c18 Don't attempt to use flags from predicated instructions.
The ARM backend can eliminate cmp instructions by reusing flags from a
nearby sub instruction with similar arguments.

Don't do that if the sub is predicated - the flags are not written
unconditionally.

Greg Clayton bded106120 Playing around with "objc_refs" over the weekend and improved it to work on a large ObjC program without running into expression timeouts. Now we get a full list of ObjC classes using a runtime function and then qsort the result. Also added code that can count all instances of each ObjC on the heap and also the total byte sizes for the object allocations.
