This patch allows to pass the gpu module name to SPIR-V module during conversion. This has many benefits as we can lookup converted to SPIR-V kernel in the symbol table. In order to avoid symbol conflicts, `"__spv__"` is added to the gpu module name to form the new one. Reviewed By: mravishankar Differential Revision: https://reviews.llvm.org/D86384
