[analyzer][NFC] Remove a non-actionable dump (#106232)

This dump, if it is ever executed, is not actionable by the user and
might produce unwanted noise in the stderr.

The original intention behind this dump, to provide maximum information
in an unexpected situation, does not outweigh the potential annoyance
caused to users who might not even realize that they witnessed an
unexpected situation.
