  [flang][OpenMP] Map `teams loop` to `teams distribute` when required.

This extends support for generic `loop` rewriting by:
1. Preventing nesting multiple worksharing loops inside each other. This
   is checked by walking the `teams loop` region searching for any
   `loop` directive whose `bind` modifier is `parallel`.
2. Preventing convert to worksharing loop if calls to unknow functions
   are found in the `loop` directive's body.

We walk the `teams loop` body to identify either of the above 2
conditions, if either of them is found to be true, we map the `loop`
directive to `distribute`.
