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.

After post-commit review and community discussion, this seems like a
reasonable direction to continue, making ownership semantics explicit in
the source using the type system.

This reverts commit r213307.
Reverting to have some on-list discussion/confirmation about the ongoing
direction of smart pointer usage in the LLVM project.

(after fixing a bug in MultiplexConsumer I noticed the ownership of the
nested consumers was implemented with raw pointers - so this fixes
that... and follows the source back to its origin pushing unique_ptr
ownership up through there too)

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.
