Don't assume LIT_EXECUTABLE points to a Python script
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: 227994
