Vedant Kumar 95a2a7f2a1 [Lexer] Don't merge macro args from different macro files 
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.
