Remove support for the fptrunc, fpext, fptoui, fptosi, uitofp and sitofp constant expressions. All places creating them have been removed beforehand, so this just removes the APIs and uses of these constant expressions in tests. With this, the only remaining FP operation that still has constant expression support is fcmp. This is part of https://discourse.llvm.org/t/rfc-remove-most-constant-expressions/63179.
