actually manage the builtin header file includes as well as the system
ones.
This one is actually debatable whether it belongs in the driver or not,
as the builtin includes are really an internal bit of implementation
goop for Clang. However, they must be included at *exactly* the right
point in the sequence of header files, which makes it essentially
impossible to have this be managed by the Frontend and the rest by the
Driver. I have terrible ideas that would "work", but I think they're
worse than putting this in the driver and making the Frontend library
even more ignorant of the environment and system on which it is being
run.
Also fix the fact that we weren't properly respecting the flags which
suppress standard system include directories.
Note that this still leaves all of the Clang tests which run CC1
directly and include builtin header files broken on Windows. I'm working
on a followup patch to address that.

encode the *exact* semantics which the header search paths internally
built by the Frontend layer have had, which is both non-user-provided,
and at times adding the implicit extern "C" bit to the directory entry.
There are lots of CC1 options that are very close, but none do quite
this, and they are all already overloaded for other purposes. In some
senses this makes the command lines more clean as it clearly indicates
which flags are exclusively used to implement internal detection of
"standard" header search paths.
Lots of the implementation of this is really crufty, due to the
surrounding cruft. It doesn't seem worth investing lots of time cleaning
this up as it isn't new, and hopefully *lots* of this code will melt
away as header search inside of the frontend becomes increasingly
trivial.

of the include flag adding component of the toolchain. Another step to
ready it for holding all the InitHeaderSearch logic.

and the C++ include management routine from the proper place when
forming preprocessor options in the driver. This is the first step to
teaching the driver to manage all of the header search paths. Currently,
these methods remain just stubs in the abstract toolchain. Subsequent
patches will flesh them out with implementations for various toolchains
based on the current code in InitHeaderSearch.cpp.

something is in an anonymous or inline namespace is actually not
useful, since you don't have to type it anyway. Fixes

that it retains source location information for the type. Aside from
general goodness (being able to walk the types described in that
information), we now have a proper representation for dependent
delegating constructors. Fixes PR10457 (for real).

The motivation for this new DiagnosticConsumer is to provide a way for tools invoking the compiler
to get its diagnostics via a libclang interface, rather than textually parsing the compiler output.
This gives us flexibility to change the compiler's textual output, but have a structured data format
for clients to use to get the diagnostics via a stable API.
I have no tests for this, but llvm-bcanalyzer so far shows that the emitted file is well-formed.
More work to follow.

Introduce a FILE_SORTED_DECLS [de]serialization record that contains
a file sorted array of file-level DeclIDs in a PCH/Module.
The rationale is to allow "targeted" deserialization of decls inside
a range of a source file.

Difference of creation time for Cocoa PCH is below the noise level.
