This commit ensures that the LLVMIR export prioritizes existing DILocalScope attribute information as location scopes over files constructed from filenames. All DILocalScope attributes contain file information, so no information is lost. The previous implementation caused the introduction of superfluous DILexicalBlockFile nodes in certain cases. The old implementation remains as a fallback when no DILocalScope is present. Reviewed By: gysit Differential Revision: https://reviews.llvm.org/D144968
