if swapchain creation fails (e.g., insane cts swapchain configs), the
swapchain gets demoted to a non-window image that is still accessed by
the frontend. this image should not ever hit corresponding zink entrypoints
for swapchain-only images, which requires a flag to test swapchain-edness

With the previous commit, we now have new builder helpers that will
allocate a temporary destination for us. So we can eliminate a lot
of the temporary naming and declarations, and build up expressions.
In a number of cases here, the code was confusingly mixing D-type
addresses with UD-immediates, or expecting a UD destination. But the
underlying values should always be positive anyway. To accomodate the
type inference restriction that the base types much match, we switch
these over to be purely UD calculations. It's cleaner to do so anyway.
Compared to the old code, this may in some cases allocate additional
temporary registers for subexpressions.

In many cases, we calculate an expression by generating a series of
instructions. We'd either overwrite the same register repeatedly,
or call vgrf(BRW_TYPE_X) repeatedly to allocate temporaries for each
intermediate step. In many cases, we overwrote the same register simply
because allocating and naming temporaries for each step was annoying.
This commit adds new builder helpers that will allocate a temporary
destination for you, using simple type interference: unary operations
use the source type, and binary operations require a matching base type
and return the largest of the two types.
The helpers return the destination register, allowing us to write in an
expression-tree style, chaining together builder operations to produce
whole values. Sort of like nir_builder. We still optionally will write
out the fs_inst pointer in case the caller wants to do things like set
predicates or saturation.

Some instructions can operate on mixed types. Typically this is
something like a binary operation with UD and UW sources resulting
in a UD destination. In order to make it easier to find the result
type of such operations, let's make a type helper that returns the
larger of the two types (but requires the base type to match).

16 bits of the first source and low 16 bits of the second source, but
actually it's the opposite. The algebraic optimization, which actually

was wrong.
Note that in the way we use it when lowering multiplications, the

In the future we will have many ALU instructions passing shared
registers to each other, and surrounding them each with moves to/from
shared registers will severely bloat the IR size coming out of NIR and
make more pointless work for copy propagation. Instead, do something
more like the ACO approach and allow values stored in the hash table to
be shared, and move the burden of emitting a mov to non-shared to
ir3_get_src(). We will then use ir3_get_src_shared() or
ir3_get_src_maybe_shared() as appropriate in cases where we can handle
shared registers or where we can handle both.
