This commit bulk updates all '.h', '.cl', '.inc', and '.cpp' files to add any missing license headers. The remaining files are generally CMake, SOURCES, scripts, markdown, etc. There are still some '.ll' files which may benefit from a license header. I can't find an example of an LLVM IR file with a license header in the rest of LLVM, but unlike most other (sub)projects, libclc has examples of LLVM IR as source files, compiled and built into the library.
