This implements the protocols and static functions proposed in SE-0246, plus some initial test coverage. It also has some rough accompanying cleanup of tgmath. It does not include the globals (on scalars or SIMD types) nor does it deprecate much in tgmath.h.

As SE-0246 gives a standard name for those functions, please deprecate for Swift 5.1 formSquareRoot and eventually squareRoot. See the comment from Steve Canon:

Even the existing method x.formSquareRoot( ) was probably ill-considered because it doesn't offer any efficiency wins, but everyone was quite gung-ho about testing out the edges of the naming conventions at that point. It's a vestigial curiosity now that we might deprecate at some future point.

By deprecating for Swift 5.1 formSquareRoot/squareRoot in favor or sqrt, we would be consistent with the availability messages for M_SQRT2/M_SQRT1_2 coming from https://github.com/apple/swift/pull/23956/files.

I’m sure Steve is well aware of his own comment :)

Deprecation would require discussion on Swift Evolution and is not a part of SE-0246.

@xwu Oh, I didn't realize it was the same person.
