This change prevents embedding identical SPIR-V section for each
target requested in fatbinary build. Instead of duplicating SPIR-V,
a new file called 'generic_ir' is added to AR archive. It contains
SPIR-V, which was used to build fatbinary. Build fallback in runtime
has been also adjusted - if 'generic_ir' file is defined in fatbinary
and there is no matching binary, then this generic SPIR-V is used to
rebuild for the requested target.
Additionally, MockOclocArgumentHelper::loadDataFromFile() was adjusted
to ensure null-termination of returned strings.
This change also removes possible undefined behavior, which was
related to reading names of files from AR archive. Previously,
if filename was shorter than requested target name, we tried to
read more memory than allowed.

Added 'link' option to ocloc CLI, which allows linking of
several IR files to single output file. Supported formats
of output file are ELF and LLVM BC.
