This patch uses the caching added in D109844 <https://reviews.llvm.org/D109844> to analyze calls. It adds a
variant of callCapturesBefore which should only be called if the object
does not escape before the call. I am happy to adjust the naming and
structure of the changes in CaptureTracking and I'll add a doc-comment
once everything is settled.

Fixes PR50220.
