This PR adds support for the SPV_KHR_linkonce_odr extension and modifies existing negative test with a positive check for the extension and proper linkage type in case when the extension is enabled. SPV_KHR_linkonce_odr adds a "LinkOnceODR" linkage type, allowing proper translation of, for example, C++ templates classes merging during linking from different modules and supporting any other cases when a global variable/function must be merged with equivalent global variable(s)/function(s) from other modules during the linking process.
