The PragmaAssumeNonNullHandler (and maybe others) passes an invalid SourceLocation to its callback, hence PrintPreprocessedOutput does not know how many lines to insert between the previous token and the pragma and does nothing. With this patch we instead assume that the unknown token is on the same line as the previous such that we can call the procedure that also emits semantically significant whitespace. Fixes bug reported here: https://reviews.llvm.org/D104601#3105044
