Broadcasting over Base._cpow with a MtlArray causes an error due to type promotion in Metalv1.3.0

MWE:

Base._cpow.(Metal.rand(Complex{Float32}, 1), 0.5f0)

ERROR: InvalidIRError: compiling MethodInstance for (::Metal.var"#broadcast_linear#216")(::MtlDeviceVector{…}, ::Base.Broadcast.Broadcasted{…}) resulted in invalid LLVM IR
