  Changed paths:
    M clang/lib/Format/ContinuationIndenter.cpp
    M clang/lib/Format/TokenAnnotator.cpp
    M clang/lib/Format/UnwrappedLineParser.cpp
    M clang/lib/Format/WhitespaceManager.cpp

  Log Message:
  -----------
  Fix various problems found by fuzzing.

1. IndexTokenSource::getNextToken cannot return nullptr; some code was
still written assuming it can; make getNextToken more resilient against
incorrect input and fix its call-sites.

2. Change various asserts that can happen due to user provided input to
conditionals in the code.
