Stanislav Mekhanoshin	50ea93a2bd	[AMDGPU] Add amdgpu-unify-metadata pass ... Multiple metadata values for records such as opencl.ocl.version, llvm.ident and similar are created after linking several modules. For some of them, notably opencl.ocl.version, this creates semantic problem because we cannot tell which version of OpenCL the composite module conforms. Moreover, such repetitions of identical values often create a huge list of unneeded metadata, which grows bitcode size both in memory and stored on disk. It can go up to several Mb when linked against our OpenCL library. Lastly, such long lists obscure reading of dumped IR. The pass unifies metadata after linking.
