nir: update nir_lower_returns to only predicate instructions when needed
Unless an if statement contains nested returns we can simply add
any following instructions to the branch without the return.
V2: fix handling if_nested_return value when there is a sibling if/loop
that doesn't contain a return. (Spotted by Ken)
V3:
- add a better comment to the new variable
- remove instructions after if when both branches return

nir: Switch the arguments to nir_foreach_function
This matches the "foreach x in container" pattern found in many other
programming languages. Generated by the following regular expression:
s/nir_foreach_function(\([^,]*\),\s*\([^,]*\))/nir_foreach_function(\2, \1)/

nir: Add return lowering pass
This commit adds a NIR pass for lowering away returns in functions. If the
return is in a loop, it is lowered to a break. If it is not in a loop,
it's lowered away by moving/deleting code as needed.
