BLORP never touches these, and they're all non-pipelined. Some

I haven't tried to benchmark this; the effect is likely to be small.
However, we may as well stop the pointless papercuts; maybe they'll

Class "ir_constant" had a bunch of constructors where the pointer member
"array_elements" had not been initialized. This could have lead to unsafe
code if something had tried to write anything to it. This patch fixes
this issue by initializing the pointer to NULL in all the constructors.
This issue was discovered by Coverity.

The SAMPLEMASK semantic should only return the bits set covered by the
current invocation. However we were always retrieving the covmask, which
returns the covered samples of the whole pixel.
When not doing per-sample invocation, this is precisely what we want.
However when doing per-sample invocation, we have to select the
sampleid'th bit and only return that. Furthermore, this means that we
have to have a 1:1 correlation for invocations and samples.
This fixes most

logic as well as what happens with MSAA x2 RTs when the shading fraction

According to the GLSL spec, if the user uses the fma() intrinsic to
generate a precise-consumed value, and you have it in your hardware, you
shouldn't split it. For a while now, we've been splitting all ffma's
up-front and then planned to fuse them later which isn't valid. Correctly
handling the GLSL behaviour fixes rendering corruptions in Tomb Raider.
The only reason why doing this possibly helped before was for ARB programs
which is handled by the previous commit.
Shader-db results on Haswell:
total instructions in shared programs: 7560300 -> 7561510 (0.02%)
instructions in affected programs: 56265 -> 57475 (2.15%)
helped: 86
HURT: 291
The only shaders in the database that are affected are from "Shadow of
Mordor" which is the first app in our database to use fma(). We could, at
some point in the future, split inexact ffma opcodes which would fix the
shader-db regressions since Shadow of Mordor doesn't ues precise. However,
this fixes a bug now and and the shader-db impact is fairly small.

A pass to lower complex (struct/array/mat) inputs/outputs to primitive
types. This allows, for example, linking that removes unused components
of a larger type which is not indirectly accessed.
In the near term, it is needed for gallium (mesa/st) support for NIR,
since only used components of a type are assigned VBO slots, and we
otherwise have no way to represent that to the driver backend. But it
should be useful for doing shader linking in NIR.

The goal is to allow the pipe driver to request something other than
TGSI, but detect whether what is getting is TGSI vs what it requested.
The pipe drivers will always have to support TGSI (and convert that into
whatever it is that they prefer), but in some cases we should be able to
skip the TGSI intermediate step (such as glsl->nir vs glsl->tgsi->nir).
I think pipe_compute_state should get similar treatment. Currently,
afaict, it has one user and one consumer, which has allowed it to be
sloppy wrt. supporting alternative IR's.

Currently, when cross validating global variables, all global variables
seen in the shaders that are part of a program are saved in a table.
When checking a variable this already exist in the table, we check both
are initialized to the same value. If the already saved variable does
not have an initializer, we copy it from the new variable.
Unfortunately this is wrong, as we are modifying something it is
constant. Also, if this modified variable is used in
another program, it will keep the initializer, when it should have none.
Instead of copying the initializer, this commit replaces the old
variable with the new one. So if we see again the same variable with an
initializer, we can compare if both are the same or not.

From the discussion, obviously it would be preferable to make
ralloc_size no longer return zeroed memory, but Juha-Pekka found that
it would break Mesa.
In <56AF1C57.2030904@gmail.com>, Juha-Pekka mentioned that patches
exist to fix i965 when ralloc_size is fixed to not zero memory, but
the patches have not made their way to mesa-dev yet.

and the hardware LDS size on SI is only 32 KiB. It isn't
correct anyway when processing multiple patches in a threadgroup.
As we potentially have any number of patches such that the
used LDS is at most the hardware LDS size, and exact size
