[Mesa-dev] [PATCH v4 58/63] radeonsi: only decompress resident textures/images when used

[Samuel Pitoiset]

When the current bound shaders don't use any bindless textures
or images, it's useless to decompress the resident resources.

v4: - inline si_*_uses_bindless_*()
v3: - rebased and updated check for compute
