Reapply working parts of CMake cleanup. This patch adds the working parts of r243503. The difference with this patch is that it doesn't include the HandleLLVMOptions.cmake file. llvm-svn: 243698

# The tests shouldn't link to any ABI library when it has been linked into
[libcxx] Make it drastically simpler to link libc++. Summary: Currently on most platforms you have to manually link the c++ abi library used with libc++ whenever you use libc++. So your typical libc++ command like invocation might look like: ``` clang++ -stdlib=libc++ foo.cpp -lc++abi ``` Having to manually link `libc++abi.so` makes it harder for libc++ to be used generically. This patch fixes that by generating a linker script for `libc++.so` that correctly links the ABI library. On linux the linker script for libc++abi would look like: ``` # libc++.so INPUT(libc++.so.1 -lc++abi) ``` With the linker script you can now use libc++ using only `-stdlib=libc++`. This is the technique that is used on FreeBSD in ordered to link cxxrt and I think it's the best approach to make our users lives simpler. The CMake option used to enable this is `LIBCXX_ENABLE_ABI_LINKER_SCRIPT`. In future I would like to enable this by default on all platforms except for Darwin.

Don't assume LIT_EXECUTABLE points to a Python script, take 2 Before this patch, the CMake build assumed LIT_EXECUTABLE pointed to a Python script, not an executable. If you were to pass in an executable, such as the result of py2exe on lit.py, the build would fall over. With this patch, the CMake build assumes LIT_EXECUTABLE is an executable. You can continue setting it to lit.py, but it will now use its shebang to find a Python interpreter. Differential Revision: http://reviews.llvm.org/D7315 llvm-svn: 228005
