The `stride` and `offset` attributes are meaningful for the "virtual"
register files (VGRFs, UNIFORMs and ATTRs). Accumulator is an ARF so
validation should check `hstride` (part of the <V,W,H> triple) and `subnr`
instead.

This ensure the region triple <V,W,H> is set correctly, in this case the
desired region is a sequential like <8,8,1>. Without the helper the
sequence we get is <0,1,0> -- which the generator currently partially
adjusts when emitting code, but is not sufficient when doing validation
earlier.
The code generated code is slightly modified. From crucible test
func.shader.subtractSaturate.uint in the fragment shader for SIMD8, the
diff looks like
```
mov(8) acc0<1>UD g21<8,8,1>UD { align1 1Q $0.dst };
-add.sat(8) g22<1>UD -acc0<0,1,0>UD g16<8,8,1>UD { align1 1Q @1 $0.dst };
+add.sat(8) g22<1>UD -acc0<8,8,1>UD g16<8,8,1>UD { align1 1Q @1 $0.dst };
```
Note that without the patch generator adjusted the hstride for acc0 used
as destination (see brw_set_dest), but kept the src region as is. For
the source, it is not clear to me why the <0,1,0> would work correctly
here since it is a scalar, but using <8,8,1> it is correct.

Setting vindex != NULL (even if it's 0) selects a struct.buffer.load opcode,
which causes LLVM to look for "index * stride + offset" in voffset and
moves "index" to vindex (i.e. not 0 anymore), but the bounds checking
(OOB_SELECT) is set to ignore vindex. Setting vindex = NULL selects
a raw.buffer.load opcode.

For something as basic as read_invocation(x, 0), we were emitting:
mov(8) vgrf67:D, 0d
find_live_channel(8) vgrf236:UD, NoMask
broadcast(8) vgrf237:D, vgrf67:D, vgrf236+0.0<0>:UD NoMask
broadcast(8) vgrf235+0.0:W, vgrf197+0.0:W, vgrf237+0.0<0>:D NoMask
mov(8) vgrf234+0.0:W, vgrf235+0.0<0>:W
This is way overcomplicated - if the invocation is a constant, we can
simply emit a single MOV which reads the desired channel index. Not
only that, but it's difficult to clean up:
1. If this expression appears multiple times, CSE will find all the
redundant emit_uniformize(invocation) and get rid of the duplicate
(find_live_channel+broadcast) on future instructions.
2. Copy propagation will put the 0d directly in the first broadcast.
3. Dead code elimination will get rid of the vgrf67 temp holding 0.
4. Algebraic will replace the first broadcast(x, 0) with a MOV.
5. Copy propagation will put the 0d directly in the second broadcast.
6. Dead code elimination will get rid of the vgrf237 temp.
7. Algebraic will replace the second broadcast(x, 0) with a MOV.
8. Copy propagation will finally combine the two MOVs
That's at least 7-8 optimization passes and several loops through the
same passes just to clean up something we can do trivially.
