We run a ton of backend specific passes here (mostly brw_preprocess_nir)
and ought to sweep up any unused memory at this point, since we're going
to hang on to this NIR for as long as the linked program lives.
Currently, ir3 backend compiler is lowering integer multiplication from:
dst = a * b
to:
dst = (al * bl) + (ah * bl << 16) + (al * bh << 16)
by emitting this code:
mull.u tmp0, a, b ; mul low, i.e. al * bl
madsh.m16 tmp1, a, b, tmp0 ; mul-add shift high mix, i.e. ah * bl << 16
madsh.m16 dst, b, a, tmp1 ; i.e. al * bh << 16
which at that point has very low chances of being optimized.
This patch adds a new nir_algebraic.AlgebraicPass to performs this
lowering during NIR algebraic optimization passes, giving it a better
chance for optimizing the resulting code.

For umul_low (al * bl), zero is returned if the low 16-bits word of either
source is zero.
for imadsh_mix16 (ah * bl << 16 + c), c is returned if either 'ah' or 'bl'
is zero.
A couple of nir_search_helpers are added:
is_upper_half_zero() returns true if the highest word of all components of
an integer NIR alu src are zero.
is_lower_half_zero() returns true if the lowest word of all components of
an integer nir alu src are zero.

'umul_low' is the low 32-bits of unsigned integer multiply. It maps
directly to ir3's MULL_U.
'imadsh_mix16' is multiply add with shift and mix, an ir3 specific
instruction that maps directly to ir3's IMADSH_M16.
Both are necessary for the lowering of integer multiplication on
Freedreno, which will be introduced later in this series.

Commit 2282ec0a refactored drawable creation across various platforms
into a new dri2_create_drawable helper function.
The GBM code in platform_drm.c code passed in dri2_surf->gbm_surf as the
loaderPrivate, while most other backends passed in dri2_surf directly.
To try and handle this, the patch checked if dri2_surf->gbm_surf was
non-NULL, and if so, presumed that the caller is the DRM platform and
we should use the dri2_surf->gbm_surf pointer.
This worked for most platforms, which calloc their dri2_surf structure,
zeroing the data. Unfortunately, platform_x11.c used malloc, leaving
most of the dri2_surf as garbage. In particular, dri2_surf->gbm_surf
was often non-NULL, causing dri2_create_drawable to try and use it,
passing a garbage pointer to the createNewDrawable hook, usually leading
to a SIGBUS or SIGSEGV when trying to dereference that bad pointer.
Since most callers calloc the data, make platform_x11.c follow suit.

the same preloaded descriptors were used for loads and stores. However,
when the preloading was removed in 16be87c904, the existing logic was
kept despite it not being necessary anymore. The comment above
force_dcc_off() only mentions stores, so only force DCC off for stores.

Depending on whether compiled with frame-pointer or not, the temporary
memory location used for the bp parameter in these macros are referenced
relative to the stack pointer or the frame pointer.
Hence we can never reference that parameter when we've modified either
the stack pointer or the frame pointer, because then the compiler would
generate an incorrect stack reference.
Fix this by pushing the temporary memory parameter on a known location on
the stack before modifying the stack- and frame pointers.
Also in case of failuire RPCI channel is not closed which lead to vmx
running out of channels.

There were two errors. First, the pass could propagate conditional
modifiers from an instruction that writes on flag register to an
instruction that writes a different flag register. For example,
cmp.nz.f0.0(16) null:F, vgrf6:F, vgrf5:F
cmp.nz.f0.1(16) null:F, vgrf6:F, vgrf5:F
could be come
cmp.nz.f0.0(16) null:F, vgrf6:F, vgrf5:F
Second, if an instruction writes f0.1 has it's condition propagated, the
modified instruction will incorrectly write flag f0.0. For example,
linterp(16) vgrf6:F, g2:F, attr0:F
cmp.z.f0.1(16) null:F, vgrf6:F, vgrf5:F
(-f0.1) discard_jump(16) (null):UD
could become
linterp.z.f0.0(16) vgrf6:F, g2:F, attr0:F
(-f0.1) discard_jump(16) (null):UD
None of these cases will occur currently. The only time we use f0.1 is
for generating discard intrinsics. In all those cases, we generate a
squence like:
cmp.nz.f0.0(16) vgrf7:F, vgrf6:F, vgrf5:F
(+f0.1) cmp.z(16) null:D, vgrf7:D, 0d
(-f0.1) discard_jump(16) (null):UD
Due to the mixed types and incompatible conditions, this sequence would
never see any cmod propagation. The next patch will change this.
No shader-db changes on any Intel platform.
