[swift-evolution] [proposal] extra if syntax

[Austin Zheng]

This is vaguely similar to "if/else and switch as expressions" in the
Commonly Proposed list (
https://github.com/apple/swift-evolution/blob/master/commonly_proposed.md),
and probably needs far more justification. (I would argue that it's worse,
since it's less expressive and, as a statement, cannot be composed.)
