Without this change the imported entity defined under DILexicalBlockFile (in the test example) will be created under DW_TAG_lexical_block corresponded with DILexicalBlockFile.
This will not happen for a local variable.

Notice that I am fine with creating lexical block entry for each DILexicalBlockFile, but either we do so for all local decls or for none.
