Jason suggested adding an assert(function->impl) here. All callers
of this function actually want ->impl, so I decided just to change
the API.
We also change the nir_lower_io_to_temporaries API here. All but one
caller passed nir_shader_get_entrypoint(), and with the previous commit,
it now uses a nir_function_impl internally. Folding this change in
avoids the need to change it and change it back.
v2: Fix one call I missed in ir3_compiler (caught by Eric).

This changes the pass internals to work with a nir_function_impl
directly rather than a nir_function. The next patch will change
the API.

This requires emitting a series of copies at the top of the program
from each output variable to the corresponding temporary. The initial
copy can be skipped for non-framebuffer fetch outputs whose initial
value is undefined, and the final copy needs to be skipped for
read-only outputs (i.e. gl_LastFragData), since it would be illegal to
emit a store output intrinsic for it.

Since it will gain support to lower inputs, give it a more generic name.
