Fix PR14732 by handling all kinds of IMPLICIT_DEF live ranges.

Remove the declspecs from small alignments that we can force with
a union. These don't actually work for by-value function arguments, and
MSVC warns if they exist even while (we hope) it aligns the argument
correctly due to the other union member.
This means MSVC will miss out on optimizations based on the alignment of
the buffer, but really, there aren't that many for x86 and MSVC is
likely not doing a great job of optimizing LLVM and Clang anyways.

Begin sketching out the process interface.
The coding style used here is not LLVM's style because this is modeled
after a Boost interface and thus done in the style of a candidate C++
standard library interface. I'll probably end up proposing it as
a standard C++ library if it proves to be reasonably portable and
useful.
This is just the most basic parts of the interface -- getting the
process ID out of it. However, it helps sketch out some of the boiler
plate such as the base class, derived class, shared code, and static
factory function. It also introduces a unittest so that I can
incrementally ensure this stuff works.
However, I've not even compiled this code for Windows yet. I'll try to
fix any Windows fallout from the bots, and if I can't fix it I'll revert
and get someone on Windows to help out. There isn't a lot more that is
mandatory, so soon I'll switch to just stubbing out the Windows side and
get Michael Spencer to help with implementation as he can test it
directly.

Start sketching out a roadmap for better subprocess management in the
LLVM libraries. Also, clean up the doxygen and formatting of the
existing interfaces.
With this change I'm calling the existing interface "legacy" because I'd
like to replace it with something much better. My end goal is to expose
a common set of interfaces for inspecting various properties of
a process, and implementations to expose those both for the current
process and for child processes. This will also expose more rich
interfaces for spawning and controling a subprocess, notably to use
system calls like wait3 and wait4 where available and gather detailed
resource usage stats about the subprocess.
My plan (discussed with Michael Spencer on IRC) is to base this loosely
around the proposed Boost.Process interface, but to implement
a relatively small subset of that functionality based around the needs
of LLVM, Clang, the Clang driver, etc.
