This removes the select constant expression, as part of https://discourse.llvm.org/t/rfc-remove-most-constant-expressions/63179. Uses of this expressions have already been removed in advance, so this just removes related infrastructure and updates tests. Differential Revision: https://reviews.llvm.org/D145382
