gh-132732: Automatically constant evaluate pure operations (GH-132733)

This adds a "macro" to the optimizer DSL called "REPLACE_OPCODE_IF_EVALUATES_PURE", which allows automatically constant evaluating a bytecode body if certain inputs have no side effects upon evaluations (such as ints, strings, and floats).
