Erik Eckstein	35097b5a71	Optimizer: simplify unconditional_checked_cast to existential metatypes. ... Replace `unconditional_checked_cast` to an existential metatype with an `init_existential_metatype`, it the source is a conforming type. Note that init_existential_metatype is better than unconditional_checked_cast because it does not need to do any runtime casting.	2025-03-07 15:59:33 +01:00
