Tom Stellard 44b6117dfd Implement accurate log2 function
Use the implementation was ported from the AMD builtin library rather
than LLVM Intrinsics.

This has been tested with piglit, OpenCV, and the ocl conformance tests.

Tom Stellard d768ac0395 Add __CLC_ prefix to all macro definitions in headers
libclc was defining and undefing GENTYPE and several other macros with
common names in its header files.  This was preventing applications from
defining macros with identical names as command line arguments to the
compiler, because the definitions in the header files were masking the
macros defined as compiler arguements.
