This Cl adds function variables to the SPIR-V output. This requires some refactoring to split function instructions and variables apart in the builder. Bug: tint:5 Change-Id: I4d0045f5a02311cf9a2803929c66c648278e3734 Reviewed-on: https://dawn-review.googlesource.com/c/tint/+/18600 Reviewed-by: David Neto <dneto@google.com>
