freedreno/ir3: Apply the max upload limit to initial range setup

There's no sense in planning out an upload that we won't be able to
actually upload due to the limit.  This means that we can keep making
other loads pushable, even after we find one that wouldn't be, and we
don't fill the const file with UBO data for a load we couldn't promote.

total instructions in shared programs: 8096655 -> 8044344 (-0.65%)
total constlen in shared programs: 1447824 -> 1411384 (-2.52%)
total cat6 in shared programs: 97824 -> 89983 (-8.02%)
