This writes the whole destination register in a single builder call.
Eventually, VEC will write the whole destination register in one go,
allowing better visibility into how it is defined.

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.

This has no changes in shader-db or fossil-db, surprisingly, but at
least CSEL will be useful shortly. Presumably the others may matter
somewhere.

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.

When internal compute shaders are used, existing shader images are not
fully unbound, which means any image can be bound, even if the internal
shader doesn't use images.
This strengthens the code by applying it only to images used by internal
compute shaders.

Note: As a matter of fact, this change by itself makes vdpau on r600 works again.
Indeed, r600 sets the stride value with vertex_buffer_index as the r600 index;
vertex_buffer_index was set to zero at the vl_compositor/init_buffers() stage on
the three elements. As a consequence of this typo the stride value was overwritten
to zero. This was breaking vdpau.
