Add support for SPV_KHR_non_semantic_info This entails a couple of changes: - Allowing unknown OpExtInstImport that begin with the prefix `NonSemantic.` - Allowing OpExtInst that reference any of those sets to contain unknown ext inst instruction numbers, and assume the format is always a series of IDs as guaranteed by the extension. - Allowing those OpExtInst to appear in the types/variables/constants section. - Not stripping OpString in the --strip-debug pass, since it may be referenced by these non-semantic OpExtInsts. - Stripping them instead in the --strip-reflect pass. * Add adjacency validation of non-semantic OpExtInst - We validate and test that OpExtInst cannot appear before or between OpPhi instructions, or before/between OpFunctionParameter instructions. * Change non-semantic extinst type to single value * Add helper function spvExtInstIsNonSemantic() which will check if the extinst set is non-semantic or not, either the unknown generic value or any future recognised non-semantic set. * Add test of a complex non-semantic extinst * Use DefUseManager in StripDebugInfoPass to strip some OpStrings * Any OpString used by a non-semantic instruction cannot be stripped, all others can so we search for uses to see if each string can be removed. * We only do this if the non-semantic debug info extension is enabled, otherwise all strings can be trivially removed. * Silence -Winconsistent-missing-override in protobufs
