This allows clang-cl to self-host cleanly with no magic setup
steps required.
After this patch, all you have to do is set CC=CXX=clang-cl and
run cmake -G Ninja.
These changes only exist to support C++ features which are
unsupported in clang-cl, so regardless of whether the user
specifies they want to use them, we still have to disable them.

Summary:
* add_llvm_tool and add_llvm_library now add install-${name} targets to install specific components
* added installhdrs target to install just the LLVM headers
* The above changes only apply for single-configuration generators (Ninja, Makefiles...), not for multi-configuration generators (Visual Studio, Xcode...)

This was added in r188351 to fix a naming conflict between the
profile_rt-static and profile_rt-shared who both ended up in
lib/profile_rt.lib.
The change also affected other libraries (like libclang), and
users are reporting that they find it surprising that there's
no longer a libclang.lib. Since the profile_rt naming conflict
doesn't seem to exist any more, I think we can remove this.

Add the missing `DEPENDS` keyword. r225319 did almost the right thing
(I didn't notice the problem with it because `Kaleidoscope-Ch8` wasn't
building at all).

Summary:
This in turn allows us to use #includes with cgo that rely on CMake
provided include directories which is particularly useful for handling
generated headers that aren't reasonable to put in an "installable"
location.

A shared library (unlike a .a), has its dependencies recorded in the library and
we can pass PRIVATE to target_link_libraries.
This patch then removes some bogus dependencies when using
BUILD_SHARED_LIBS=ON. For example, we go from
build lib/CodeGen/CMakeFiles/LLVMCodeGen.dir/AggressiveAntiDepBreaker.cpp.o:
CXX_COMPILER /home/espindola/llvm/llvm/lib/CodeGen/AggressiveAntiDepBreaker.cpp
|| include/llvm/IR/intrinsics_gen lib/libLLVMSupport.so
lib/libLLVMCore.so lib/libLLVMBitReader.so
lib/libLLVMTransformUtils.so lib/libLLVMInstCombine.so
lib/libLLVMScalarOpts.so lib/libLLVMipa.so lib/libLLVMAnalysis.so
lib/libLLVMMCParser.so lib/libLLVMMC.so lib/libLLVMObject.so
lib/libLLVMTarget.so lib/libLLVMProfileData.so
to
build lib/CodeGen/CMakeFiles/LLVMCodeGen.dir/AggressiveAntiDepBreaker.cpp.o:
CXX_COMPILER /home/espindola/llvm/llvm/lib/CodeGen/AggressiveAntiDepBreaker.cpp
|| include/llvm/IR/intrinsics_gen lib/libLLVMSupport.so
lib/libLLVMCore.so lib/libLLVMTransformUtils.so

lib/libLLVMTarget.so
In fact, build.ninja goes from 5231028 bytes to 4896759 bytes.
With this, old verisons of bfd ld (2.24 is OK, 2.23 warns) will print a bogus
warning when building with BUILD_SHARED_LIBS.

to the C++ code that is built along side the Go bindings when testing
them.

It dropped required functions for plugins with gnu ld 2.20 and 2.21.

LLVM :: Feature/load_module.ll
Hello: bin/opt: symbol lookup error: lib/LLVMHello.so: undefined symbol: _ZN4llvm11raw_ostream13write_escapedENS_9StringRefEb

I think we should inspect linker's version or behavior to introduce --gc-sections for --export-dynamic.

to globally be controlled. Individual targets (e.g. ExceptionDemo) can
still override this by using LLVM_REQUIRE_RTTI and LLVM_REQUIRE_EH if
they need to be compiled with RTTI or exception handling respectively.

For example, c-index-test.exe requires just libclang.dll (its import library).
When libraries in libclang were not PRIVATE but PUBLIC, c-index-test required libraries transitive by libclang.
Note, on mingw with BUILD_SHARED_LIBS, library dependencies would become more strict.
In principle, required libraries should be "required in its source file".
This will help to detect missing dependencies.

FIXME: Make this configurable.
FIXME: "ENABLE_SHARED" doesn't make sense, since it is used just for plugins. We may rename it.
I introduced config.enable_shared in r120273.
