[Mesa-dev] [PATCH 2/3] nir: drop name and label when serializing

[Timothy Arceri]

Dropping these makes the shaders more generic which can make it
better when using the serialized NIR as a key for in memory shader
caches such as what we do for radeonsi.

Also it just means we can write/read less to and from the disk cache.
