Modify the add_header_files_for_glob() function to only add files
that do exist, rather than all matches of the glob. This fixes CMake
error when one of the include directories (which happen to include
/usr/include) contain broken symlinks.

Previously adding header and table gen files was conditional on using an IDE. Since these files have the `HEADER_FILE_ONLY` attribute applied they are ignored as sources by all non-IDE generators, so there is really no reason not to include them.
Additionally having the CMake always include these files allows the CMake-server to include them in the sources list for targets, which is valuable to anyone using CMake-server integrated tools.

Cmake function llvm_check_source_file_list currently only accepts paths
relative to current CMAKE_SOURCE_DIR or relative to argument SOURCE_DIR.
Extend it to accept any path, including absolute ones.

Summary:
Currently LLVM has no way to support configuring for IDE's like CLion. Like XCode and MSVC's IDE, CLion needs to see all of the headers and tablegen files in order to properly parse the sources.
This patch adds an `LLVM_ENABLE_IDE` option which can be used to configure for IDE's in general. It is used by `LLVMProcessSources.cmake` to determine if the extra source files should be added to the target.
Unfortunately because of the low level of `LLVMProcessSources.cmake`, I'm not sure where the `LLVM_ENABLE_IDE` option should live. I choose `HandleLLVMOptions.cmake` so that out-of-tree Clang builds would correctly configure the option by default.

The motivation is to be able to check sources outside the current
directory. See D31363 for example usage.

Since header files are not compilation units, CMake does not require
you to specify them in the CMakeLists.txt file. As a result, unless a
header file is explicitly added, CMake won't know about it, and when
generating IDE-based projects, CMake won't put the header files into
the IDE project. LLVM currently tries to deal with this in two ways:
1) It looks for all .h files that are in the project directory, and
adds those.
2) llvm_add_library() understands the ADDITIONAL_HEADERS argument,
which allows one to list an arbitrary list of headers.
This patch takes things one step further. It adds the ability for
llvm_add_library() to take an ADDITIONAL_HEADER_DIRS argument, which
will specify a list of folders which CMake will glob for header files.
Furthermore, it will glob not only for .h files, but also for .inc
files.
Included in this CL is an update to one of the existing users of
ADDITIONAL_HEADERS to use this new argument instead, to serve as an
illustration of how this cleans up the CMake.
The big advantage of this new approach is that until now, there was no
way for the IDE projects to locate the header files that are in the
include tree. In other words, if you are in, for example,
lib/DebugInfo/DWARF, the corresponding includes for this project will
be located under include/llvm/DebugInfo/DWARF. Now, in the
CMakeLists.txt for lib/DebugInfo/DWARF, you can simply write:
ADDITIONAL_HEADER_DIRS
../../include/llvm/DebugInfo/DWARF
as an argument to llvm_add_library(), and all header files will get
added to the IDE project.

I am sure it'd not be required any more.
In trunk, all of tablegen's users depend on ${TABLEGEN_OUTPUT} as not file dependency but inter-target dependency.

ADDITIONAL_HEADERS is intended to add header files for IDEs as hint.
For example:
add_llvm_library(LLVMSupport
Host.cpp
ADDITIONAL_HEADERS
Unix/Host.inc
Windows/Host.inc

Makefiles, the CMake files in every other part of the LLVM tree, and
sanity.
This should also restore the output tree structure of all the unit
tests, sorry for breaking that, and thanks for letting me know.
The fundamental change is to put a CMakeLists.txt file in the unittest
directory, with a single test binary produced from it. This has several
advantages:
- No more weird directory stripping in the unittest macro, allowing it
to be used more readily in other projects.
- No more directory prefixes on all the source files.
- Allows correct and precise use of LLVM's per-directory dependency
system.
- Allows use of the checking logic for source files that have not been
added to the CMake build. This uncovered a file being skipped with
CMake in LLVM and one in Clang's unit tests.
- Makes Specifying conditional compilation or other custom logic for JIT
tests easier.
It did require adding the concept of an explicit 'optional' source file
to the CMake build so that the missing-file check can skip cases where
the file is *supposed* to be missing. =]
This is another chunk of refactoring the CMake build in order to make it
usable for other clients like CompilerRT / ASan / TSan.
Note that this is interdependent with a Clang CMake change.

This is useful in case someone who works with the config&make build
system forgot to add a file to its CMakeLists.txt. Instead of
obtaining undefined references at link time, cmake will complain at
configure time on the first build after a svn update.
