1a75b081 - [SILGen] Fix `swift_once` initializer signature for lazy global var

[SILGen] Fix `swift_once` initializer signature for lazy global var `Builtin.once` has type `(Builtin.RawPointer, (Builtin.RawPointer) -> ())` at Swift level, but lazy global init passes its initializer as `() -> ()`, so their callee and caller signatures doesn't match.
