blob does makes it easier to compare cmdstream.

glx/windows: Fix compilation with -Werror-format
Fix compilation where the DWORD type is used with a format, after
-Werror-format added by
c9c1e261.
Some Win32 API types are different fundamental types in the 32-bit and
64-bit versions. This problem is then further compounded by the fact
that whilst both 32-bit Cygwin and 32-bit MinGW use the ILP32 data
model, 64-bit MinGW uses the LLP64 data model, but 64-bit Cygwin uses
the LP64 data model. This makes it near impossible to write printf
format specifiers which are correct for all those targets.
In the Win32 API, DWORD is an unsigned, 32-bit type. So, it is defined
in terms of an unsigned long, except in the LP64 data model used by
64-bit Cygwin, where it is an unsigned int.
It should always be safe to cast it to unsigned int and use %u or %x.

isl: Mark enum isl_channel_select packed so it becomes 1 byte.
I recently discovered that the following code lead to valgrind errors:
struct isl_swizzle swizzle = ISL_SWIZZLE_IDENTITY;
VALGRIND_CHECK_MEM_IS_DEFINED(&swizzle, sizeof(swizzle));
which is surprising, because struct isl_swizzle is simply:
struct isl_swizzle {
enum isl_channel_select r:4;
enum isl_channel_select g:4;
enum isl_channel_select b:4;
enum isl_channel_select a:4;
};
and the above code initializes all of them with a C99 initializer.
Iván Briano reminded me that C99 initializers don't necessarily zero
padding. A quick inspection revealed that sizeof(struct isl_swizzle)
was 4 (rather than the expected 2). Ian Romanick suggested changing
it to uint16_t, since this is essentially dicing up an unsigned, and
that worked.
This patch marks enum isl_channel_select packed, changing its size
from 4 bytes to 1 byte. This then makes struct isl_swizzle 2 bytes,
with no bogus padding fields. This eliminates valgrind undefined
memory warnings.
These isl_swizzle values become part of our BLORP blit program keys,
which are then hashed. This undefined padding was being included in
the hashing, possibly leading to issues. I originally saw this error
when running KHR-GL45.texture_size_promotion.functional in iris under
valgrind.

egl/x11: calloc dri2_surf so it's properly zeroed
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.

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.

intel/fs: Improve discard_if code generation
Previously we would blindly emit an sequence like:
mov(1) f0.1<1>UW g1.14<0,1,0>UW
...
cmp.l.f0(16) g7<1>F g5<8,8,1>F 0x41700000F /* 15F */
(+f0.1) cmp.z.f0.1(16) null<1>D g7<8,8,1>D 0D
The first move sets the flags based on the initial execution mask.
Later discard sequences contain a predicated compare that can only
remove more SIMD channels. Often times the only user of the result from
the first compare is the second compare. Instead, generate a sequence
like
mov(1) f0.1<1>UW g1.14<0,1,0>UW
...
cmp.l.f0(16) g7<1>F g5<8,8,1>F 0x41700000F /* 15F */
(+f0.1) cmp.ge.f0.1(8) null<1>F g5<8,8,1>F 0x41700000F /* 15F */

intel/fs: Fix flag_subreg handling in cmod propagation
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.
v2: Fix typo in comment in test case subtract_delete_compare_other_flag.

intel/blorp: Handle SINT/UINT clamping on blits.
This patch makes blorp_blit handle SINT<->UINT blit value clamping.
After reading the source's integer data (which is expanded to 32-bit),
we either IMAX with 0 (for SINT -> UINT, to clamp negative numbers) or
UMIN with (1 << 31) - 1 (for UINT -> SINT, to clamp positive numbers
outside of the representable range).
Such blits are not allowed by the OpenGL or Vulkan APIs directly:
The Vulkan 1.1 spec for vkCmdBlitImage says:
"Integer formats can only be converted to other integer formats with
the same signedness."
The GL 4.5 spec for glBlitFramebuffer says:
"An INVALID_OPERATION error is generated if format conversions are
not supported, which occurs under any of the following conditions:
[...]
* The read buffer contains unsigned integer values and any draw
buffer does not contain unsigned integer values.
* The read buffer contains signed integer values and any draw buffer
does not contain signed integer values."
However, they are useful for other operations, such as texture upload
and download, which typically are implemented via blorp_blit(). i965
has code to fall back in this case (which the next commit will delete),
and Gallium expects blit() to handle this case for texture upload.

Both GLSL IR and NIR perform the same mod -> floor lowering for 32-bit

lowered drcp precision loss, and handles mod(x, x) = 0 directly. This
works well...assuming nir_lower_double_ops actually gets an fmod op to
lower in the first place.
The previous patches enabled NIR-based lowering for the remaining
