AMDGPU/GlobalISel: Explicitly track d16 for image legalization

We were trying to guess at the original IR type for image intrinsics
after legalization to figure out if they were d16, but this didn't
work. Explicitly track if this is a d16 operation or not in the
opcode, as is done for the buffer intrinsics.

The OpenCL library is using f32 image writes with a dmask of 15 for
some reason, and this was incorrectly switching them to use d16. Fixes
image failures in the OpenCL conformance test. The equivalent dmask
for loads doesn't even select in either selector.
