clang-format: Properly reset nested AnnotatedLine structure.
This fixes llvm.org/PR17682.
Without this patch, the following code leads to invalid reads/writes:
DEBUG({
return aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa +
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa;
});
#if a
#else
#endif
Because of the #if-#else structure, the code is formatted and annotated
twice and becauce of the nested block, the annotated lines form a
hierarchical structure. This structure was not properly reset between
runs.
