Measured on RDNA2 (gfx1035) in review: image_store with DIM 2D through a
1D T# writes texel x for every y, including y = 0xffffffff. The T# type
decides the addressing and DIM only how many address VGPRs are read. The
store no longer drops y != 0.

The test now pins the second store at y = 1 with dmask 0x5: texel x holds
its components 0 and 2, components 1 and 3 are 0.
