Sort all of Clang's files under 'lib', and fix up the broken headers
...
uncovered.
This required manually correcting all of the incorrect main-module
headers I could find, and running the new llvm/utils/sort_includes.py
script over the files.
I also manually added quite a few missing headers that were uncovered by
shuffling the order or moving headers up to be main-module-headers.

Format strings: %D, %U, and %O are valid on Darwin (same as %d, %u, %o).

These will warn under -Wformat-non-iso, and will still be rejected
outright on other platforms.

Remove ScanfArgType and bake that logic into ArgType.

This is useful for example for %n in printf, which expects
a pointer to int with the same logic for checking as %d
would have in scanf.

format string is a pointer to int.

Make -Wformat walk the typedef chain when looking for size_t, etc.
...
Clang's -Wformat fix-its currently suggest using "%zu" for values of
type size_t (in C99 or C++11 mode). However, for a type such as
std::vector<T>::size_type, it does not notice that type is actually
typedeffed to size_t, and instead suggests a format for the underlying
type, such as "%lu" or "%u".
This commit makes the format string fix mechanism walk the typedef chain
so that it notices if the type is size_t, even if that isn't "at the
top".

Format string analysis: give 'q' its own enumerator.

Make -Wformat fix-its preserve original conversion specifiers.
...
This commit makes PrintfSpecifier::fixType() and ScanfSpecifier::fixType()
only fix a conversion specification enough that Clang wouldn't warn about it,
as opposed to always changing it to use the "canonical" conversion specifier.
(PR11975)
This preserves the user's choice of conversion specifier in cases like:
printf("%a", (long double)1);
where we previously suggested "%Lf", we now suggest "%La"
printf("%x", (long)1);
where we previously suggested "%ld", we now suggest "%lx".
