CMake: Deprecate using llvm-config to detect llvm installation
Summary:
clang currently uses llvm-config to determine the installation paths
for llvm's headers and binaries. clang is also using LLVM's cmake
files to determine other information about the LLVM build, like
LLVM_LIBDIR_SUFFIX, LLVM_VERSION_*, etc. Since the installation
paths are also available via the cmake files, we can simplify the code
by only relying on information from cmake about the LLVM install and
dropping the use of llvm-config altogether.
In addition to simplifying the code, the cmake files have more
accurate information about the llvm installation paths. llvm-config
assumes that the lib, bin, and cmake directories are always located
in the same place relative to the path of the llvm-config executable.
This can be wrong if a user decides to install headers, binaries
or libraries to a non-standard location: e.g. static libraries
installed to /usr/lib/llvm6.0/
This patch takes the first step towards dropping llvm-config by
removing the automatic detection of llvm-config (users can still
manually supply a path to llvm-config by passing
-DLLVM_CONFIG=/usr/bin/llvm-config to cmake) and adding a
deprecation warning when users try to use this option.

[Clang][Driver] Re-use the calling process instead of creating a new process for the cc1 invocation
With this patch, the clang tool will now call the -cc1 invocation directly inside the same process. Previously, the -cc1 invocation was creating, and waiting for, a new process.
This patch therefore reduces the number of created processes during a build, thus it reduces build times on platforms where process creation can be costly (Windows) and/or impacted by a antivirus.
It also makes debugging a bit easier, as there's no need to attach to the secondary -cc1 process anymore, breakpoints will be hit inside the same process.
Crashes or signaling inside the -cc1 invocation will have the same side-effect as before, and will be reported through the same means.
This behavior can be controlled at compile-time through the CLANG_SPAWN_CC1 cmake flag, which defaults to OFF. Setting it to ON will revert to the previous behavior, where any -cc1 invocation will create/fork a secondary process.
At run-time, it is also possible to tweak the CLANG_SPAWN_CC1 environment variable. Setting it and will override the compile-time setting. A value of 0 calls -cc1 inside the calling process; a value of 1 will create a secondary process, as before.

Simplify Clang's version number configuration in CMake.
Currently, the Clang version is computed as follows:
1. LLVM defines major, minor, and patch versions, all statically set. Today,
these are 4, 0, and 0, respectively.
2. The static version numbers are combined into PACKAGE_VERSION along with a
suffix, so the result today looks like "4.0.0svn".
3. Clang extracts CLANG_VERSION from PACKAGE_VERSION using a regexp. The regexp
allows the patch level to omitted, and drops any non-digit trailing values.
Today, this result looks like "4.0.0".
4. CLANG_VERSION is then split further into CLANG_VERSION_MAJOR and
CLANG_VERSION_MINOR. Today, these resolve to 4 and 0, respectively.
5. If CLANG_VERSION matches a regexp with three version components, then
CLANG_VERSION_PATCHLEVEL is extracted and the CLANG_HAS_VERSION_PATCHLEVEL
variable is set to 1. Today, these values are 0 and 1, respectively.
6. The CLANG_VERSION_* variables (and CLANG_HAS_VERSION_PATCHLEVEL) are
configured into [llvm/tools/clang/]include/clang/Basic/Version.inc
verbatim by CMake.
7. In [llvm/tools/clang/]include/clang/Basic/Version.h, macros are defined
conditionally, based on CLANG_HAS_VERSION_PATCHLEVEL, to compute
CLANG_VERSION_STRING as either a two- or three-level version number. Today,
this value is "4.0.0", because despite the patchlevel being 0, it was
matched by regexp and is thus "HAS"ed by the preprocessor. This string is
then used wherever Clang's "version" is needed [*].
[*] Including, notably, by compiler-rt, for computing its installation path.
This change collapses steps 2-5 by defaulting Clang to use LLVM's (non-string)
version components for the Clang version (see [*] for why not PACKAGE_VERSION),
and collapses steps 6 and 7 by simply writing CLANG_VERSION_STRING into
Version.inc. The Clang version today always uses the patchlevel form, so the
collapsed Version.inc does not have logic for a version without a patch level.
Historically speaking, this technique began with the VER file in r82085 (which
survives in the form of the regexp in #3). The major, minor, and patchlevel
versions were introduced by r106863 (which remains in #4-6). The VER file itself
was deleted in favor of the LLVM version number in r106914. On the LLVM side,
the individual LLVM_VERSION_MAJOR, LLVM_VERSION_MINOR, and PACKAGE_VERSION
weren't introduced for nearly two more years, until r150405.

[analyzer] Improved cmake configuration for Z3
Summary:
Enhanced support for Z3 in the cmake configuration of clang; now it is possible to specify any arbitrary Z3 install prefix (CLANG_ANALYZER_Z3_PREFIX) to cmake with lib (or bin) and include folders. Before the patch only in cmake default locations
were searched (https://cmake.org/cmake/help/v3.4/command/find_path.html).
Specifying any CLANG_ANALYZER_Z3_PREFIX will force also CLANG_ANALYZER_BUILD_Z3 to ON.
Removed also Z3 4.5 version requirement since it was not checked, and now Clang works with Z3 4.7

So, instead, I propose the following:
Instead of having clang-7.0 in bin/, we will have clang-7

Fix missing build dependency on omp_gen.
Summary:
`include/llvm/Frontend/OpenMP/CMakeLists.txt` creates a new target
called `omp_gen` which builds the generated include file `OMP.h.inc`.
This target must therefore be a dependency of every compilation step
whose transitive #include dependencies contain `OMP.h.inc`, or else
it's possible for builds to fail if Ninja (or make or whatever)
schedules that compilation step before building `OMP.h.inc` at all.
A few of those dependencies are currently missing, which leads to
intermittent build failures, depending on the order that Ninja (or
whatever) happens to schedule its commands. As far as I can see,
compiles in `clang/lib/CodeGen`, `clang/lib/Frontend`, and
`clang/examples` all depend transitivily on `OMP.h.inc` (usually via
`clang/AST/AST.h`), but don't have the formal dependency in the ninja
graph.
Adding `omp_gen` to the dependencies of `clang-tablegen-targets` seems
to be the way to get the missing dependency into the `clang/examples`
subdirectory. This also fixes the other two clang subdirectories, as
far as I can see.
