Adjust TypeMember for NonSemantic spec (#2033)
It no longer has a Scope (parent) parameter. It results in several changes including how to determine DIBuilder to use for debug info generation. The patch also fixes a bug of incorrect debug info assignment in case of recursion DebugInfo inst generation. Signed-off-by: Sidorov, Dmitry <[email protected]> Original commit: KhronosGroup/SPIRV-LLVM-Translator@01679ce
