Summary: Atomic buffer operations do not work (and trap on gfx9) when the components are unaligned, even if their sum is aligned. Previously, we generated an offset of 4156 without an SGPR by splitting it as 4095 + 61 (immediate + inline constant). The highest offset for which we can do this correctly is 4156 = 4092 + 64.
