As reported in llvm bugzilla 32377.
Here’s a patch to add preinclude of stdc-predef.h.
The gcc documentation says “On GNU/Linux, <stdc-predef.h> is pre-included.” See https://gcc.gnu.org/gcc-4.8/porting_to.html;
The preinclude is inhibited with –ffreestanding.
Basically I fixed the failing test cases by adding –ffreestanding which inhibits this behavior.
I fixed all the failing tests, including some in extra/test, there's a separate patch for that which is linked here
Note: this is a recommit after a test failure took down the original (r318669)

This complements the clang_getSkippedRanges function which returns skipped ranges filtered by a specific file.
This function is useful when all the ranges are desired (and a lot more efficient than the equivalent of asking for the ranges file by file, since the implementation of clang_getSkippedRanges iterates over all ranges anyway).

This will be needed for the next commit that allows to switch the default
C++ library which would otherwise make these tests fail.

The host libstdc++ may be horribly broken and we want the fake one to be
picked up. This workaround is lame but I don't see a better way.

This provides both a more uniform interface and makes libclang behave like
clang tooling wrt relative paths against argv[0]. This is necessary for
finding paths to a c++ standard library relative to a clang binary given
in a compilation database. It can also be used to find paths relative to
libclang.so if the full path to it is passed in.

One of the problems libclang tests has running under Windows is memory
allocated in libclang.dll but being freed in the test executable, possibly
by a different memory manager. This patch exposes a new export function,
clang_free(), used to free any allocated memory with the same libclang.dll
memory manager that allocated the memory.

No functionality changed, this is a purely mechanical cleanup to ensure
the #include order remains consistent across the project.

Add module dependencies (header files, module map files) to the list of
files to check when deciding whether to rebuild a preamble. That fixes
using preambles with module imports so long as they are in
non-overridden files.
My intent is to use to unify the existing dependency collectors to the
new “DependencyCollectory” interface from this commit, starting with the
DependencyFileGenerator.

There are a couple of issues with writing VFS maps that are awkward to
fix within the current mutually recursive approach. Instead, replace
the algorithm with an iterative version that uses an explicit stack of
directories.
Includes tests for cases the old approach was tripping on.

Checking if a path starts with another path isn't sufficient for
determining if one is contained within the heirarchy of the other.
We need to ensure that the substring ends at a directory boundary.

The YAMLParser has its own escaped string representation, and does not
handle octal escape sequences. When writing the virtual file system to a
YAML file, use yaml::escape().

The current API only supports adding 'virtual file path' -> 'real file path' mappings.
