This extends the target builtin support to allow language specific annotations
(i.e. LANGBUILTIN). This is to allow MSVC compatibility whilst retaining the
ability to have EABI targets use a __builtin_ prefix. This is merely to allow
uniformity in the EABI case where the unprefixed name is provided as an alias in
the header.

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.

and language-specific initialization. Use this to allow ASTUnit to
create a preprocessor object *before* loading the AST file. No actual
functionality change.

inconsistent with the type that the builtin *should* have, forget
about the builtin altogether: we don't want subsequence analyses,
CodeGen, etc., to think that we have a proper builtin function.
C is protected from errors here because it allows one to use a
library builtin without having a declaration, and detects inconsistent
(re-)declarations of builtins during declaration merging. C++ was
unprotected, and therefore would crash.
Fixes PR8839.

a specific language. We are adding such language info. by
extensing Builtins.def and via a language flag added
to LIBBUILTIN/BUILTIN and check for that when deciding
a name is builtin or not. Implements //rdar://8689273.

represent builtins that have the "scanf" attribution (via the format attribute) just
like we do with printf functions. Follow-up work is needed to add similar support
for fscanf et al.
This is to support format-string checking for scanf functions.

registered when PCH wasn't being used. We should always install (in BuiltinInfo)
information about target-specific builtins, but we shouldn't register any builtin
identifier infos. This fixes the build of apps that use PCH and target specific
builtins together.

preprocessor and initialize it early in clang-cc. This
ensures that __has_builtin works in all modes, not just
when ASTContext is around.
