Reland "[analyzer] Harden safeguards for Z3 query times" (#97298)
This is exactly as originally landed in #95129,
but now the minimal Z3 version was increased to meet this change in #96682.
https://discourse.llvm.org/t/bump-minimal-z3-requirements-from-4-7-1-to-4-8-9/79664/4
---
This patch is a functional change.
https://discourse.llvm.org/t/analyzer-rfc-taming-z3-query-times/79520
As a result of this patch, individual Z3 queries in refutation will be
bound by 300ms. Every report equivalence class will be processed in at
most 1 second.
The heuristic should have only really marginal observable impact -
except for the cases when we had big report eqclasses with long-running
(15s) Z3 queries, where previously CSA effectively halted. After this
patch, CSA will tackle such extreme cases as well.
(cherry picked from commit eacc3b3504be061f7334410dd0eb599688ba103a)
