Floating-point constants such as infinity or greatestFiniteMagnitude can make one's code slower than necessary because they are computed each time they're used. By contrast, pi is as fast as possible. Here, we follow the example of pi and speed up other constants.

(In this PR, signalingNaN is deliberately untouched because it's got some interesting platform-specific behavior.)

Resolves SR-6919.
