This helps with code like in clang's test/CodeGen/debug-info-line.c where we have multiple #line directives within a single lexical block and want to generate only a single block that contains each file change.

| | | | | | | | | this clang will use .debug_frame in, for example, clang -g -c -m32 test.c This matches gcc's behaviour.
