These are very similar to the related function in nir_lower_io except
that they don't handle per-vertex or packed things (that could be added,
in theory) and they take a more detailed size/align function pointer.
One day, we should consider switching nir_lower_io over to using the
more detailed size/align functions and then we could make it use these
helpers instead of having its own.

This commit introduces a new nir_deref.h header for helpers that are
less common and really only needed by a few heavy-duty passes. In this
header is a new struct for representing a full deref path which can be
walked in either direction.
v2 (Jason Ekstrand):
- Assert that deref != NULL (Caio)
- Fill _short_path with 0xdeadbeef in debug builds when not used (Caio)
- Make nir_deref_path a typedef (Rob)
