nir/large_constants: De-duplicate constants

If a function has a constant and is called more than once, after
inlining we may end up with different variables representing the same
constant.  This commit look into the data and de-duplicate them.

The first pass now will collect the constant data in a per variable
buffer, then de-duplication happens (by sorting then linear walk), and
the second pass will use the data in var->data.location.

One side-effect of the current implementation is that constants will
be reordered.  If this turns out to be a problem is something that can
be fixed.

An alternative strategy considered was to perform this in a
per-function basis and then merge the results, the problem is that we
would have to fix up the offsets during the merge.  Given the data we
have, the current patch is good enough.

lima/gp: Fix problem with complex moves

When writing the scheduler, we forgot that you can't read the complex
unit in certain sources because it gets overwritten to 0 or 1. Fixing
this turned out to be possible without giving up and reducing
GPIR_VALUE_REG_NUM to 10, although it was difficult in a way I didn't
expect. There can be at most 4 next-max nodes that can't have moves
scheduled in the complex slot, so it actually isn't a problem for
getting the number of next-max nodes at 5 or lower. However, it is a
problem for stores. If a given node is a next-max node whose move cannot
go in the complex slot *and* is used by a store that we decide to
schedule, we have to reserve one of the non-complex slots for a move
instead of all the slots, or we can wind up in a situation where only
the complex slot is free and we fail the move. This means that we have
to add another term to the reservation logic, for stores whose children
cannot be in the complex slot.

lima/gpir: Rework the scheduler

Now, we do scheduling at the same time as value register allocation. The
ready list now acts similarly to the array of registers in
value_regalloc, keeping us from running out of slots. Before this, the
value register allocator wasn't aware of the scheduling constraints of
the actual machine, which meant that it sometimes chose the wrong false
dependencies to insert. Now, we assign value registers at the same time
as we actually schedule instructions, making its choices reflect reality
much better. It was also conservative in some cases where the new scheme
doesn't have to be. For example, in something like:

1 = ld_att
2 = ld_uni
3 = add 1, 2

It's possible that one of 1 and 2 can't be scheduled in the same
instruction as 3, meaning that a move needs to be inserted, so the value
register allocator needs to assume that this sequence requires two
registers. But when actually scheduling, we could discover that 1, 2,
and 3 can all be scheduled together, so that they only require one
register. The new scheduler speculatively inserts the instruction under
consideration, as well as all of its child load instructions, and then
counts the number of live value registers after all is said and done.
This lets us be more aggressive with scheduling when we're close to the
limit.

With the new scheduler, the kmscube vertex shader is now scheduled in 40
instructions, versus 66 before.
