Simplify for-loops with straight-line control flow.

If we know that for-loop won't escape early due to a `continue`,
`break` or `return`, and the loop conforms to ES2 structure, we
are guaranteed to run the full number of iterations across all
executing lanes. In this case, we don't need to use a loop mask.
