Instead of using CLANG_ENABLE_STATIC_ANALYZER for use of the
static analyzer in both clang and clang-tidy, add a second
toggle CLANG_TIDY_ENABLE_STATIC_ANALYZER.
This allows enabling the static analyzer in clang-tidy while
disabling it in clang.

This patch adds the missing information to the LF_BUILDINFO record, which allows for rebuilding a .CPP without any external dependency but the .OBJ itself (other than the compiler).
Some external tools that we are using (Recode, Live++) are extracting the information to reproduce a build without any knowledge of the build system. The LF_BUILDINFO stores a full path to the compiler, the PWD (CWD at program startup), a relative or absolute path to the TU, and the full CC1 command line. The command line needs to be freestanding (not depend on any environment variables). In the same way, MSVC doesn't store the provided command-line, but an expanded version (somehow their equivalent of CC1) which is also freestanding.
For more information see PR36198 and D43002.

f8990feb12 enabled installing PIC version of both libclang.a and
libclang.so when LIBCLANG_BUILD_STATIC is ON. But it broke the no-PIC
build when LLVM_ENABLE_PIC=OFF with the following error:
```
CMake Error at
/b/s/w/ir/cache/builder/src/third_party/llvm/clang/tools/libclang/CMakeLists.txt:123
(target_compile_definitions):
target_compile_definitions called with non-compilable target type
```
This is because as the code loops through ${name} and ${name}_static, it
introduced a side effect, which is adding an empty libclang_static to
targets. Later target_compile_definitions is called on libclang_static.
That function requires that target must have been created by a command
such as add_executable() or add_library(), so it crashed.
The solution is to not naively loop through both libclang and
libclang_static, but only the ones that are actually added by
llvm_add_library(). Here's the library build type to library target name
mapping:
| SHARED only | libclang |
| STATIC only | libclang |
| SHARED and STATIC | libclang and libclang_static |
So only when SHARED and STATIC are both set should we loop through two
targets. Explicitly parse the STATIC argument and set the list
accordingly.

This reverts commit f8990feb12.
When LIBCLANG_BUILD_STATIC=ON and LLVM_ENABLE_PIC=ON, PIC version of
libclang.a and libclang.so are built as expected. However libclang.a is
not installed. Looking at the macro llvm_add_library(), when both SHARED
and STATIC are set, it renames the static library to ${name}_static and
then adds it to targets. But when add_clang_library() calls install, it
only checks if ${name} is in targets.
To work around this issue, loop through both ${name} and ${name}_static
and install both of them if they're in targets. This is still correct if
only shared or static library is built. In those cases, only ${name} is
added to targets and cmake install will generate the right install
script depending on the library's type.
Test Plan:
cmake with LIBCLANG_BUILD_STATIC=ON and then ninja install, from master
and this diff. Compare the result directory trees. Confirm that only
difference is the added libclang.a.

Previously, the tablegen() cmake command, which defines custom
commands for running tablegen, included several hardcoded paths. This
becomes unwieldy as there are more users for which these paths are
insufficient. For most targets, cmake uses include_directories() and
the INCLUDE_DIRECTORIES directory property to specify include paths.
This change picks up the INCLUDE_DIRECTORIES property and adds it
to the include path used when running tablegen. As a side effect, this
allows us to remove several hard coded paths to tablegen that are redundant
with specified include_directories().
I haven't removed the hardcoded path to CMAKE_CURRENT_SOURCE_DIR, which
seems generically useful. There are several users in clang which apparently
don't have the current directory as an include_directories(). This could
be considered separately.
The new version of this path uses list APPEND rather than list TRANSFORM,
in order to be compatible with cmake 3.4.3. If we update to cmake 3.12 then
we can use list TRANSFORM instead.
