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.
The SPIR spec states that all OpenCL built-in functions should be
overloadable and mangled, to ensure consistency.
Add the overload attribute to functions which were missing them:
work dimensions, memory barriers and fences, and events.

Also fix get_global_id to consider offset
No idea how to add this for ptx, so they are stuck with the old get_global_id
implementation.
