"bank_conflict_cycles" cannot affect this, it came with later commit.

    anv: Add support for the variablePointers feature

    Not to be confused with variablePointersStorageBuffer which is the
    subset of VK_KHR_variable_pointers required to enable the extension.
    This means we now have "full" support for variable pointers.
