Merge #11132: Document assumptions that are being made to avoid NULL pointer dereferences
fdc3293 Document assumptions that are being made to avoid NULL pointer dereferences (practicalswift)
Pull request description:
Document assumptions (via `assert(…)`:s) that are being made avoid `NULL` pointer dereferences.
Rationale:
* Make it clear to human reviewers and non-human static analyzers that what might look like potential `NULL` pointer dereferences are written the way they are intentionally (these cases are currently flagged by various static analyzers).
