[ConstExpr] Remove select constant expression

Browse Source 
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.
