Replace 'unsigned short' with 'uint16_t' in a packed data structure for consistency with other fields and to be explicit about bit count.

We were incorrectly computing where to insert a member if it was replacing
a previous member that was before the insert point.

With this fix, only changed regions will be replaced in vim's buffer.
Thereby, marks should mostly be left intact. Furthermore, this is a
better fix for the performance problem in conjunction with
'foldmethod=syntax' (see r186660).

helper function. This leaves both trivial cases handled entirely in
helper functions and merely manages the list of allocas to process in
the run method.

The next step will be to handle all of the trivial promotion work prior
to even creating the core class and the subsequent simplifications that
enables.

a single block into the helper routine. This takes advantage of the fact
that we can directly replace uses prior to any store with undef to
simplify matters and unconditionally promote allocas only used within
one block.

I've removed the special handling for the case of no stores existing.
This has no semantic effect but might slow things down. I'll fix that in
a later patch when I refactor this entire thing to be easier to manage
the different cases.

handles the general cases.

The hope is to refactor this so that we don't end up building the entire
class for the trivial cases. I also want to lift a lot of the early
pre-processing in the initial segment of run() into a separate routine,
and really none of it needs to happen inside the primary promotion
class.

These routines in particular used none of the actual state in the
promotion class, so they don't really make sense as members.

This struct is nicely independent of everything else, and we already
needed a foward declaration here. It's simpler to just define it
immediately.

The functionality is equivalent to the GCC attribute. Variables of tagged
types will be warned about as unused if they are not used in any way
except for possible (even non-trivial) ctors/dtors called. Useful for tagging
classes like std::string (which is not part of this commit).

Every #include is surrounded by #if 0 in order to comment it out, which adds
lines. That is fixed up right after, but that all can be inside #if part
that is not processed, so fix up also after every end of a conditional part.

Diag ID is used throughout clang as a sentinel id meaning "this is an
invalid diagnostic id."  Confusingly, Diag ID maps to a valid, usable,
diagnostic id.  Instead, start diagnostic ids at ID one.

Incidently, remove an unused element from StaticDiagInfo.
