Replaces an iterate and test bit in a bitmask loop by a
loop only iterating over the bits set in the bitmask.
v2: Use _mesa_bit_scan{,64} instead of open coding.
v3: Use u_bit_scan{,64} instead of _mesa_bit_scan{,64}.

Replaces an iterate and test bit in a bitmask loop by a

The bitmask used here for iteration is a combination
of different enabled masks present for texture units.

Instead use the internal gl_shader_stage enum everywhere. This
makes things more consistent and gets rid of unnecessary
conversions.
Ideally it would be nice to remove the Type field from gl_shader
altogether but currently it is used to differentiate between
gl_shader and gl_shader_program in the ShaderObjects hash table.

We still need to recompile the passthrough shader when this value
changes, as it also affects the output vertex count. But otherwise,
we can eliminate recompiles on Gen8+.
We probably want to do this for Gen7 as well, but that requires
rewriting the input release code to use a loop, which is a trade-off
I'd need to consider in more detail.

Fixes three GL44-CTS.tessellation_shader subtests:
- max_patch_vertices
- single.max_patch_vertices
- tessellation_control_to_tessellation_evaluation.gl_PatchVerticesIn
These use gl_PatchVerticesIn in the TES, but don't link against a
TCS (which would allow the linker to lower it to a constant). We had
no handling for the system value in the backend, so it would just
assert fail.

We've had some trouble in the past with copying integers around via
float pointers, as the C compiler sometimes uses x87 floating point
registers to load values on 32-bit systems. Passing the
gl_constant_value union should be safer.
To avoid churn, this patch creates a "GLfloat *value" variable so
existing uses can stay the same.
Not observed to fix anything, but I was in the area adding more integer
state vars, and thought it'd be wise.

The images struct is an uninitialized local variable on the stack. If the
callback returns 0, the struct might not have been updated and so should
be considered uninitialized. Currently the code ignores the return value,
which (depending on stack contents) might end up in reading a non-zero
value from images.image_mask and dereferencing further fields.
Another solution would be to initialize image_mask with 0, but checking
the return value seems more sensible and it is what Gallium is doing.
v2: fix typos in commit message,
fix indentation,
remove unnecessary parentheses and pointer dereference to keep line
length reasonable.

This was removed in d9546b0c5d and replced with the precise_trig driconf
option. However, we still need precise trig in the Vulkan driver so this
commit brings back the environment variable and compiler->precise_trig is
effectively the logical OR of the two.

Pulling DF uniforms from pull constant buffer generates messages like:
send(4) g12<1>DF g12<0,1,0>F
sampler ld SIMD4x2 Surface = 1 Sampler = 0 mlen 1 rlen 1
which produces GPU hangs in Cherryview/Braswell:
"For 64-bit Align1 operation or multiplication of dwords in CHV,
source horizontal stride must be aligned to qword."
This seems to be documented in the Cherryview PRM, Volume 7, Page 843:
"When source or destination datatype is 64b or operation is integer
DWord multiply, regioning in Align1 must follow these rules:
1. Source and Destination horizontal stride must be aligned to the
same qword."
We should set the destination type to UD, D, or F so that
the register stride checker doesn't notice. The destination type of
send messages is basically irrelevant anyway.

Pulling DF inputs from the URB generates messages like:
send(8) g23<1>DF g1<8,8,1>UD
urb 3 SIMD8 read mlen 1 rlen 2 { align1 1Q };
which makes the simulator angry:
"For 64-bit Align1 operation or multiplication of dwords in CHV,
source horizontal stride must be aligned to qword."
This seems to be documented in the Cherryview PRM, Volume 7, Page 823:
"When source or destination datatype is 64b or operation is integer
DWord multiply, regioning in Align1 must follow these rules:

Setting the source horizontal stride to QWord is insane, as it's the
message header containing 8 URB handles in a single 32-bit DWord.
Instead, we should whack the destination type to UD, D, or F so that
the register stride checker doesn't notice. The destination type of
send messages is basically irrelevant anyway.

Cherryview/Broxton annoyingly have a minimum number of VS URB entries
of 34, which is not a multiple of 8. When the VS size is less than 9,
the number of VS entries has to be a multiple of 8.
Notably, BLORP programmed the minimum number of VS URB entries (34), with
a size of 1 (less than 9), which is invalid.
It seemed like this could be a problem in the regular URB code as well,
so I went ahead and updated that to be safe.

ISTR having suggested this during review of the recent FP64 changes to
the SIMD lowering pass, but it doesn't look like it was taken into
account in the end. Using the fs_reg::component_size helper instead
of this open-coded variant makes sure that the stride is taken into
account correctly. Fixes at least the following piglit tests with
spilling forced on (since otherwise regs_written would be calculated
incorrectly and the spilling code would be rather confused about how
much data needs to be spilled):

allocation.
I haven't found any mention of this in the hardware docs, but
experimentally what seems to be going on is that when the per-thread
scratch slot size is changed between two pipelined draw calls, shader
invocations using the old and new scratch size setting may end up
being executed in parallel, causing their scratch offset calculations
to be based in a different partitioning of the scratch space, which
can cause their thread-local scratch space to overlap leading to
cross-thread scratch corruption.
I've been experimenting with alternative workarounds, like emitting a
PIPE_CONTROL with DC flush and CS stall between draw (or dispatch
compute) calls using different per-thread scratch allocation settings,
or avoiding reuse of the scratch BO if the per-thread scratch
allocation doesn't exactly match the original. Both seem to be as
effective as this workaround, but they have potential performance
implications, while this should be basically for free.
Fixes over 40 failures in our CI system with spilling forced on
(including CTS, dEQP and Piglit failures) on a number of different
platforms from Gen4 to Gen9. The 'glsl-max-varyings' piglit test
seems to be able to reproduce this bug consistently in the vertex
shader on at least Gen4, Gen8 and Gen9 with spilling forced on.

This will be used to find out what per-thread slot size a previously
allocated scratch BO was used with in order to fix a hardware race
condition without introducing additional stalls or memory allocations.
Instead of calling brw_get_scratch_bo() manually from the various
codegen functions, call a new helper function that keeps track of the
per-thread scratch size and conditionally allocates a larger scratch
BO.

power of two.
The bitwise arithmetic trick used in brw_get_scratch_size() to clamp
the scratch allocation to 1KB has the unintended side effect that it
will cause us to allocate 2x the required amount of scratch space if
the original per-thread scratch size happened to be already a power of
two. Instead use the obvious MAX2 idiom to clamp the scratch
allocation to the expected range.

Two dEQP tests expect INVALID_VALUE errors for negative width/height
parameters, but get INVALID_OPERATION because they haven't actually
created a destination image. This is arguably not a bug in Mesa, as
there's no specified ordering of error conditions.
However, it's also really easy to make the tests pass, and there's
no real harm in doing these checks earlier.

In the Vulkan driver, we have the generation number (a compile time
constant) but not necessarily the brw_device_info struct. I meant
to rework the function to take a generation number instead of a
brw_device_info pointer to accomodate this. But I forgot, and left
it taking a brw_device_info pointer, while making Vulkan pass the
generation number (8, 9, ...) directly. This led to crashes.
