The lexer sets the end location of macro arguments incorrectly *if*, while merging consecutive args to fit into a single SLocEntry, it finds args which come from different macro files. Fix the issue by using separate SLocEntries in this situation. This fixes a code coverage crasher (rdar://problem/26181005). Because the lexer reported end locations for certain macro args incorrectly, we would generate bogus coverage mappings with negative line offsets.
