dfa629a1 - [SIL] Fix memInstMustInitialize for builtins.

[SIL] Fix memInstMustInitialize for builtins. The function's switch previously fell-through to the SILInstructionKind::StoreWeakInst case which cast the instruction (a BuiltinInst) to StoreWeakInst and then called isInitializationOfDest on it.
