This adds a preprocessor callback for the `__has_include` and
`__has_include_next` directives.
Successful checking for the presence of a header should add it to the list of
header dependencies so this overrides the callback in the dependency scanner.
Patch by Pete Cooper with some additions by me.

Summary:
This commit fixes a bug where passing extra dependency entries
(using -fdepfile-entry) would result in -MP incorrectly emitting
a phony target for the input file, and no phony target for the
first extra dependency.
The extra dependencies are added first to the filename vector in
DFGImpl. That clashed with the emission of the phony targets, as
the code assumed that the first index always correspond to the
input file.

It's possible for a header to be a symlink to another header. In this
case both will be represented by clang::FileEntry with the same UID and
they'll use the same clang::HeaderFileInfo.
If you include both headers and use some single-inclusion mechanism
like a header guard or #import, one header will get a FileChanged
callback, and another FileSkipped.
So that we get an accurate dependency file, we therefore need to also
implement the FileSkipped callback in dependency scanning.

files: include the .pcm file itself in the .d output, rather than including its
own input files. Other forms of module file continue to be transparent for .d
output.
Arguably, the input files for the .pcm file are still inputs to the
compilation, but that's unnecessary for make-like build systems (where the
mtime of the .pcm file is sufficient) and harmful for smarter build systems
that know about module files and want to track only the local dependencies.

Summary:
Clang sanitizers, such as AddressSanitizer, ThreadSanitizer, MemorySanitizer,
Control Flow Integrity and others, use blacklists to specify which types / functions
should not be instrumented to avoid false positives or suppress known failures.
This change adds the blacklist filenames to the list of dependencies of the rules,
generated with -M/-MM/-MD/-MMD. This lets CMake/Ninja recognize that certain
C/C++/ObjC files need to be recompiled (if a blacklist is updated).

Backslash followed by # in a filename should have both characters
escaped, if you do it the way GNU Make wants. GCC doesn't, so we do
it the way GCC does rather than the way GNU Make wants.

When writing a dependency (.d) file, if space or # is immediately
preceded by one or more backslashes, escape the backslashes as well as
the space or # character. Otherwise leave backslash alone.
This straddles the fence between BSD Make (which does no escaping at
all, and does not support space or # in filespecs) and GNU Make (which
does support escaping, but will fall back to the filespec as-written
if the escaping doesn't match an existing file).

NMake is a Make-like builder that comes with Microsoft Visual Studio.
Jom (https://wiki.qt.io/Jom) is an NMake-compatible build tool.
Dependency files for NMake/Jom need to use double-quotes to wrap
filespecs containing special characters, instead of the backslash
escapes that GNU Make wants.
Adds the -MV option, which specifies to use double-quotes as needed
instead of backslash escapes when writing the dependency file.

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.

This is because the PCH is tied to the module files, if one of the module files changes or gets removed
the build system should re-build the PCH file.
