Auto merge of #66294 - davidhewitt:const_fn_memoization, r=oli-obk
Add memoization for const function evaluations When a const function is being evaluated, as long as all its arguments are zero-sized-types (or it has no arguments) then we can trivially memoize the evaluation result using the existing query mechanism. With thanks to @oli-obk for mentoring me through this at RustFest Barcelona. r? @oli-obk
