Summary

This is part of a series of changes to enable generating more
efficient code for C++ "noexcept" functions. See also the RFC,
https://discourse.llvm.org/t/rfc-add-call-unwindabort-to-llvm-ir/62543

In previous commits, we added the core Instruction support for
'unwindabort'. This commit adds support for its semantics to the
IR-level transforms and analyses.

Depends on D141915
