The map of FileChange structs here was storing two disjoint types of
information:
1. A pointer to the Module that an #include directive implicitly
imported
2. A FileID and FileType for an included file. These would be left
uninitialized in the Module case.
This change splits these two kinds of information into their own maps,
which both simplifies how we access either and avoids the undefined
behaviour we were hitting due to the uninitialized fields in the
included file case.
Mostly NFC, but fixes some errors found by self-host with ubsan.

Currently -fms-extensions controls this behavior, which doesn't make
much sense. It means we can't identify what is and isn't a system header
when compiling our own preprocessed output, because #line doesn't
represent this information.
If someone is feeding Clang's preprocessed output to another compiler,
they can use this flag.
Fixes PR20553.

It is very common to include headers with DOS-style line endings, such
as windows.h, from source files with Unix-style line endings.
Previously, we would end up with mixed line endings and #endifs that
appeared to be on the same line:
#if 0 /* expanded by -frewrite-includes */
#include <windows.h>^M#endif /* expanded by -frewrite-includes */
Clang treats either of \r or \n as a line ending character, so this is
purely a cosmetic issue.
This has no automated test because most Unix tools on Windows will
implictly convert CRLF to LF when reading files, making it very hard to
detect line ending mismatches. FileCheck doesn't understand {{\r}}
either.
Fixes PR20552.

According to the gcc docs, -include uses the current working directory
for the lookup instead of the main source file.
This patch gets rid of NormalizeIncludePath (which relied on an
implementation detail of FileManager / FileEntry for the include path
logic to work), and instead hands the correct lookup information down to
LookupFile.
This will allow us to change the FileEntry's behavior regarding its Name
caching.

The rewrite facility's footprint is small so it's not worth going to these
lengths to support disabling at configure time, particularly since key compiler
features now depend on it.
Meanwhile the Objective-C rewriters have been moved under the
ENABLE_CLANG_ARCMT umbrella for now as they're comparatively heavy and still
potentially worth excluding from lightweight builds.
Tests are now passing with any combination of feature flags. The flags
historically haven't been tested by LLVM's build servers so caveat emptor.
