This gathers a number of sources into a contiguous vector register.
Eventually, the plan is that it will use a MOV for a single source,
or LOAD_PAYLOAD for multiple sources. For now, it emits a series of
MOVs to allow us to rewrite a bunch of existing code to use the new
helper, then change them all over at once later.

When emitting a sampler message, we allocate a temporary destination
large enough to hold 4 values (or 5 for sparse). This is the maximum
size needed to hold any result. However, we shrink the size written by
the sampler message to skip writing any trailing components that NIR
tells us are never read. So we may not write the entire temporary.
The NIR texture instruction has a destination VGRF which is sized
assuming that all components are present. We issue a LOAD_PAYLOAD
instruction to copy our sampler result temporary to the NIR destination.
When we reduce the response length of the sampler messages, then some of
these temporary components have undefined values. The correct way to
indicate that is by using a BAD_FILE source. Unfortunately, we were
naively reading offsets of the temporary that were never written, but
are still part of a larger VGRF. This complicates things.
For example, sampling and only using RGB (not RGBA) was producing this:
txl_logical(8) (written: 3) vgrf3+0.0:F, ...
undef(8) (written: 4) vgrf4:UD
load_payload(8) (written: 4) vgrf4:F, vgrf3+0.0:F, vgrf3+1.0:F, vgrf3+2.0:F, vgrf3+3.0:F
The last source, vgrf3+3.0:F, is undefined, and should be BAD_FILE.
Doing so allows VGRF splitting and other optimizations to work better.

If there's only a single instruction in a basic block, then removing it
would create an empty block. We seem to have trouble representing those
as there are no instructions with an IP inside the block; several places
mess up connections. While most blocks end in control flow instructions
(which are rarely eliminated), ones preceding a DO instruction may end
in an ordinary instruction. This makes such blocks tricky to merge with
adjacent blocks - they may be between loops. Any optimization pass may
may find such an instruction and want to eliminate it, and most of them
are unprepared to perform such CFG link surgery. Nor do we want to make
every pass aware of this issue.
To work around this, we simply replace an instruction with a NOP when
removing it from a block containing only that instruction, leaving the
block in place.

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).

Align16 is only used on Gfx9, while Align1 is used on Gfx11+. We can
decode both kinds of encodings in the same function with a simple
devinfo check. One snag is that the align16 encodings didn't have a
separate exec_type field, but we can just pass 0.
This lets us have a single function named brw_type_decode_for_3src,
which is much less of a mouthful.
