HLSL: Fix #1163: treat buffers as references when calling functions.

This continues to prevent writing output buffers (out from a function),
but fixes the problem where the copy-in/out was not getting done.

Making everything work will require knowing both in/out-ness and bufferness,
but these are currently mutually exclusive, because both are storage
qualifiers.
