struct nu_handle is hashed and deduplicated using struct nu_handle_key, which ignored
parent_deref. That means all instructions will use the first parent_deref when rewriting
the sources.

Avoid this by not including the parent deref in the struct, and instead querying it
when needed.

44fa9c8326 nir/lower_tex: Reinstate LSB to MSB shift
Some checks are pending
macOS-CI / macOS-CI (dri) (push) Waiting to run
Details
macOS-CI / macOS-CI (xlib) (push) Waiting to run
Details 
lower_sx10_external and lower_sx12_external are used for
LSB aligned formats such as DRM_FORMAT_S010, which are typically
used by software decoders. Unlike MSB aligned 10/12 bit formats
used by hardware decoders such as P010 they need to manually
get "shifted" in order to correctly map to the 0-1 range.

In the commit mentioned below the corresponding code got removed,
probably because it got confused with similar sounding code in
the common path - and because we don't have tests on the CI for the
affected formats yet.

Note: the formats in question are not yet supported in Vulkan.
