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

to traverse the list of blocks backwards.

spirv: Expand workaround for OpControlBarrier on old GLSLang

which is an incorrect translation of glsl barrier().

GLSLang, prior to c3f1cdfa, emitted the OpControlBarrier with
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.

glsl: Hard-code noise to zero in builtin_functions.cpp

Version 4.4 of the GLSL spec changed the definition of noise*() to
always return zero and earlier versions of the spec allowed zero as a
valid implementation.

All drivers, as far as I can tell, unconditionally call lower_noise()
today which turns ir_unop_noise into zero.  We've got a 10-year-old
comment in there saying "In the future, ir_unop_noise may be replaced by
a call to a function that implements noise."  Well, it's the future now
and we've not yet gotten around to that.  In the mean time, the GLSL
spec has made doing so illegal.

To make things worse, we then pretend to handle the opcode in
glsl_to_nir, ir_to_mesa, and st_glsl_to_tgsi even though it should never
get there given the lowering.  The lowering in st_glsl_to_tgsi defines
noise*() to be 0.5 which is an illegal implementation of the noise
functions according to pre-4.4 specs.  We also have opcodes for this in
NIR which are never used because, again, we always call lower_noise().

Let's just kill the whole opcode and make builtin_builder.cpp build a
bunch of functions that just return zero.

intel/fs: Coalesce when the src live range is contained in the dst

Consider the following case:

    // g119-123 are written somewhere above
    mul.sat(16)   g67<1>F    g6.4<0,1,0>F   g125<8,8,1>F

    mul.sat(16)   g71<1>F    g6.6<0,1,0>F   g125<8,8,1>F
    mov(16)       g119<1>F   g67<8,8,1>F
    mov(16)       g121<1>F   g69<8,8,1>F
    mov(16)       g123<1>F   g71<8,8,1>F

We should be able to coalesce it into

    mul.sat(16)   g119<1>F   g6.4<0,1,0>F   g125<8,8,1>F
    mul.sat(16)   g121<1>F   g6.5<0,1,0>F   g125<8,8,1>F
    mul.sat(16)   g123<1>F   g6.6<0,1,0>F   g125<8,8,1>F

What's stopping us is an overly conservative check for writes to the two
registers being coalesced.  The check walks over the intersection of
their live ranges and checks for no writes to either one.  However,
because the register which starts the live range (the mul.sat in this
case) is inside that intersection, we flag it as a write in the
intersection and don't coalesce.  However, this case is safe because the
destination register of the copy is never read after the source is
written.
