Omit needless words: don't use typedef names as type names.

Typedefs provide weak type information in both C and Swift, so don't
use the names of typedefs when omitting needless words. This improves
a number of APIs where it looked like the words were redundant, but
the type system was deceiving us. For example:

-  func setHolding(_: NSLayoutPriority, forSubviewAt: Int)
+  func setHoldingPriority(_: NSLayoutPriority, forSubviewAt: Int)
