aco: copy-propagate p_create_vector copies of vectors

Instead of copying the operands of the other p_create_vector and labelling
the definition with label_vec, copy the operands and label it with
label_temp so that it can be copy-propagated.

This was found while removing a redundant copy in load_input_from_temps()
which removed duplicate p_create_vector instructions.

aco: decrease the uses of other copy operations after splitting/removing

For copies like v[7:8] = v[8:9], what currently happens is:
- do_copy() will skip the second dword
- the uses of the second dword will be reduced to 0
- the copy operation will be removed from the map
and v8 will never be set to v9.

So just decrease the uses of other operations after splitting or removing
the current operation, so: "v8 = v9" will be split off, it's uses reduced
and then the new copy will be done in the next iteration.

meson: correct windows-version define

nir: Actually do load/store vectorization beyond vec2

nir_opt_load_store_vectorize has an is_strided_vector() function that
looks for types with weird explicit strides.  It does so by comparing
the explicit stride against the type-size-derived typical stride.

This had a subtle bug.  Simple vector types (vec2/3/4) have no explicit
stride, so glsl_get_explicit_stride() returns 0.  This never matches the
typical stride for a vector, so is_strided_vector() would return true
for basically any vector type, causing the vectorizer to bail.

I found this by looking at a compute shader with scalar SSBO loads at
offsets 0x220, 0x224, 0x228, 0x22c.  nir_opt_load_store_vectorize would
properly vectorize the first two into a vec2 load, but would refuse to
extend it to a vec3 and ultimately vec4 load because is_strided_vector()
saw a vec2 and freaked out.

Neither ACO nor ANV do load/store vectorization before lowering derefs,
so this shouldn't affect them.  However, I'd like to fix this bug to
avoid the trap for anyone who decides to in the future.  In a branch
where anv used this lowering, this cut an additional 38% of the send
messages in the shader by properly vectorizing more things.

ir3: Fix bug with shaders that only exit via discard

discard is supposed to be a terminator, killing the thread, so that it's
possible to exit main solely by a discard e.g. inside of an infinite
loop. However, it currently isn't treated as a terminator in NIR due to
workarounds turning it into demote (d3d-style kill) and even if that
were fixed, we probably wouldn't want to treat discard_if as a jump
since otherwise the scheduler wouldn't be able to schedule things around
it. So, add this workaround which inserts jump instructions as
necessary to guarantee that the program always terminates.

This fixes a hang in dEQP-VK.graphicsfuzz.while-inside-switch, which
conditionally does a discard inside an infinite loop.

ir3: Don't double-insert the first block

which is an incorrect translation of glsl barrier().

Device instead of Workgroup for execution scope.

intel/compiler: Drop nir_lower_to_source_mods() and related handling.

I think we're unanimous in wanting to drop nir_lower_to_source_mods.
It's a bit of complexity to handle in the backend, but perhaps more
importantly, would be even more complexity to handle in nir_search.

And, it turns out that since we made other compiler improvements in the
last few years, they no longer appear to buy us anything of value.
Summarizing the results from shader-db from this patch:

 - Icelake (scalar mode)

   Instruction counts:

   - 411 helped, 598 hurt (out of 139,470 shaders)
   - 99.2% of shaders remain unaffected.  The average increase in
     instruction count in hurt programs is 1.78 instructions.
   - total instructions in shared programs: 17214951 -> 17215206 (<.01%)
   - instructions in affected programs: 1143879 -> 1144134 (0.02%)

   Cycles:

   - 1042 helped, 1357 hurt
   - total cycles in shared programs: 365613294 -> 365882263 (0.07%)
   - cycles in affected programs: 138155497 -> 138424466 (0.19%)

 - Haswell (both scalar and vector modes)

   Instruction counts:

   - 73 helped, 1680 hurt (out of 139,470 shaders)
   - 98.7% of shaders remain unaffected.  The average increase in
     instruction count in hurt programs is 1.9 instructions.
   - total instructions in shared programs: 14199527 -> 14202262 (0.02%)
   - instructions in affected programs: 446499 -> 449234 (0.61%)

   Cycles:

   - 5253 helped, 5559 hurt
   - total cycles in shared programs: 359996545 -> 360038731 (0.01%)
   - cycles in affected programs: 155897127 -> 155939313 (0.03%)

Given that ~99% of shader-db remains unaffected, and the affected
programs are hurt by about 1-2 instructions - which are all cheap
ALU instructions - this is unlikely to be measurable in terms of
any real performance impact that would affect users.

So, drop them and simplify the backend, and hopefully enable other
future simplifications in NIR.
