Rework the traversal of Objective-C categories and extensions to
consider (sub)module visibility.
The bulk of this change replaces myriad hand-rolled loops over the
linked list of Objective-C categories/extensions attached to an
interface declaration with loops using one of the four new category
iterator kinds:
visible_categories_iterator: Iterates over all visible categories
and extensions, hiding any that have their "hidden" bit set. This is
by far the most commonly used iterator.
known_categories_iterator: Iterates over all categories and
extensions, ignoring the "hidden" bit. This tends to be used for
redeclaration-like traversals.
visible_extensions_iterator: Iterates over all visible extensions,
hiding any that have their "hidden" bit set.
known_extensions_iterator: Iterates over all extensions, whether
they are visible to normal name lookup or not.
The effect of this change is that any uses of the visible_ iterators
will respect module-import visibility. See the new tests for examples.
Note that the old accessors for categories and extensions are gone;
there are *Raw() forms for some of them, for those (few) areas of the
compiler that have to manipulate the linked list of categories
directly. This is generally discouraged.

[Linker] Change module flag linking to be more extensible.
- Instead of computing a bunch of buckets of different flag types, just do an
incremental link resolving conflicts as they arise.
- This also has the advantage of making the link result deterministic and not
dependent on map iteration order.

Greg created a new API on SBProcess to get an ID that is guaranteed to be unique even in situations where underlying platforms would actually duplicate or hardcode PIDs
The Python data formatters use a per-process cache that was previously keying off the PID. Moving that to be based on this new notion of unique ID.

We want the dwarf AT_producer for assembly source files to match clang's
AT_producer. Which includes clang's version information so we can tell
which version of the compiler was used.
This is the first of two steps to allow us to do that. This is the llvm-mc
change to provide a method to set the AT_producer string. The second step,
coming soon to a clang near you, will have the clang driver pass the value
of getClangFullVersion() via an flag when invoking the integrated assembler
on assembly source files.

Added a unique integer identifier to processes. Some systems, like JTAG or other simulators, might always assign the same process ID (pid) to the processes that are being debugged. In order for scripts and the APIs to uniquely identify the processes, there needs to be another ID. Now the SBProcess class has:
uint32_t SBProcess::GetUniqueID();
This integer ID will help to truly uniquely identify a process and help with appropriate caching that can be associated with a SBProcess object.

Introduce llvm::sys::getProcessTriple() function.
In r143502, we renamed getHostTriple() to getDefaultTargetTriple()
as part of work to allow the user to supply a different default
target triple at configure time. This change also affected the JIT.
However, it is inappropriate to use the default target triple in the
JIT in most circumstances because this will not necessarily match
the current architecture used by the process, leading to illegal
instruction and other such errors at run time.
Introduce the getProcessTriple() function for use in the JIT and
its clients, and cause the JIT to use it. On architectures with a
single bitness, the host and process triples are identical. On other
architectures, the host triple represents the architecture of the
host CPU, while the process triple represents the architecture used
by the host CPU to interpret machine code within the current process.
For example, when executing 32-bit code on a 64-bit Linux machine,
the host triple may be 'x86_64-unknown-linux-gnu', while the process
triple may be 'i386-unknown-linux-gnu'.
This fixes JIT for the 32-on-64-bit (and vice versa) build on non-Apple
platforms.
