Remove support for the icmp and fcmp constant expressions. This is part of: https://discourse.llvm.org/t/rfc-remove-most-constant-expressions/63179 As usual, many of the updated tests will no longer test what they were originally intended to -- this is hard to preserve when constant expressions get removed, and in many cases just impossible as the existence of a specific kind of constant expression was the cause of the issue in the first place.
