The NameMangler Library Converts the given function descriptor to a string that represents the function's prototype.
The mangling algorithm is based on clang 3.0 Itanium mangling algorithm (http://sourcery.mentor.com/public/cxx-abi/abi.html#mangling).
The algorithm is adapted to support mangling of SPIR built-in functions and was tested on SPIR built-ins only.
The mangler supports mangling according to SPIR 1.2 and SPIR 2.0 For usage examples see unittest/spir_name_mangler.
