* change gyb files to fix error
This fixes a major perform bug involving array initialization from any
contiguously stored collection. This is not a recent regression. This fix
results in a 10,000X speedup (that's 4 zeros) for this code path:
func initializeFromSlice(_ a: [Int]) -> [Int] {
return Array<Int>(a[...])
}
A benchmark is included.
SE-0054 disallowed nesting IUO types within other types. We currently
give a warning for this, but eventually we'll either emit an error or
interpret the '!' as '?' (a plain optional).
Either way, this particular benchmark doesn't test anything different
than the one that uses plain optionals, so we should be able to remove it.
