Issue Description:

The behavior of the type checking for pow() seems rather strange in Linux Swift 3.0 Release. I'm not sure exactly what the correct behavior should be, but the inconsistency shown below is odd, and seems either like a bug, or an oddity in Swift that is difficult to rationalize. In either case, it should be fixed / improved. See REPL session:

Welcome to Swift version 3.0 (swift-3.0-RELEASE). Type :help for assistance.
  1> import Glibc
  2> pow(5, 3)
error: repl.swift:2:1: error: ambiguous use of 'pow'
pow(5, 3)
^

  2> pow(5.1, 3.1)
$R0: Double = 156.12323653407694

Note that by using: https://swiftlang.ng.bluemix.net/#/repl, you can find that this is a regression since Swift 2.2
