Mechanically add "Type" to the end of any protocol names that don't end
in "Type," "ible," or "able." Also, drop "Type" from the end of any
associated type names, except for those of the *LiteralConvertible
protocols.
There are obvious improvements to make in some of these names, which can
be handled with separate commits.
Fixes <rdar://problem/17165920> Protocols `Integer` etc should get
uglier names.

CGFloat is 32-bit on 32-bit architectures and 64-bit on 64-bit
architectures for historical reasons. Rather than having it alias
either Float (32-bit) or Double (64-bit), introduce a distinct struct
type for CGFloat. CGFloat provides a complete set of comparisons and
arithmetic operators (including tgmath functions), initializers allows
explicit conversion between it an Int, UInt, Float, and Double, as
well as conforming to all of the protocols that Float/Double do.
This formulation of CGFloat makes use of CGFloat
architecture-independent, although it still requires a number of casts.
