[Mesa-dev] [PATCH 2/2] freedreno: ir3: fix wrong return if reg is an array

[Hyunjun Ko]

Since ir3_register struct has union, it could return true even
if it's an array register accidentally when checking whether it
is address/predicate register.

Fixes: dEQP-GLES31.functional.ssbo.layout.random.arrays_of_arrays.6
