_mesa_strtod and _mesa_strtof are only used from the GLSL compiler and
the ARB_[vertex|fragment]_program code, meaning that the locale doesn't
need to be initialized before the first OpenGL context gets initialized.
So let's use explicit initialization from the one-time init code instead
of depending on a C++ compiler to initialize at image-load time.

This function only gets called while mesa is unloading, so there's
no potential of racing or multiple calls at the same time. So let's
just get rid of the locking.

There's no point in calling _mesa_destroy_shader_compiler multiple
times on exit; the resources will only be released once anyway.
So let's move the atexit-call into the part that is only called
once.

This function is for deleting per-screen resources, and the shader
compiler resources are not of such nature. Besides, dri shouldn't
need to even know about the presence of a shader compiler.
These resources will already be released when mesa gets unloaded,
and that should be sufficient.

Work-group size should always be aligned to subgroup size; this is a
basic requirement, otherwise some work-items will be no-operation.
It might make sense to refine the value according to a kernel's
resource usage, but that's a possible optimization for the future.

Since commit 104c8fc2c2aa5621261f8 the GLSL IR will be freed if NIR is
being used. This was causing it to segfault if INTEL_DEBUG=wm is set.
This patch just makes it avoid dumping the GLSL IR in that case.

This reverts commit c2ff3485b3d48749ea9dcad07bc1a691627dc3e5.
Ilia and I noticed a memory leak caused by this patch: at least with
fixed-function programs, we clone things using ProgramResourceList as
the context before reralloc makes it non-NULL.
I believe Tapani found other bugs with these patches, so I'm just going
to revert them for now and let him pursue them further.

Legacy user clipping (using gl_Position or gl_ClipVertex) is handled by
turning those into the modern gl_ClipDistance equivalents.
This is unnecessary in Core Profile: if user clipping is enabled, but
the shader doesn't write the corresponding gl_ClipDistance entry,
results are undefined. Hence, it is also unnecessary for geometry
shaders.
This patch moves the call up to run_vs(). This is equivalent for VS,
but removes the need to pass clip distances into emit_urb_writes().

According to the "URB SIMD8 Write > Write Data Payload" documentation,
"The write data payload can be between 1 and 8 message phases long."
Apparently, the simulator considers it an error if you issue an URB
SIMD8 message with only a header and no actual data to write.

The dup'ed fd owned by the nouveau_screen for a device node
must also be used as key for the winsys hash table, instead
of using the original fd passed in for a screen, to make
multi-x-screen ZaphodHeads configurations work on nouveau.
The original fd's lifetime differs from that of the nouveau_screen stored
in the hash. The hash key is the fd, and in order to compare hash entries
we fstat them, so the fd must be around for as long as the screen is.
This is an extension of the fix in commit a59f2bb1 (nouveau: dup fd
before passing it to device).

brw_miptree_layout_2d tries to ensure that mt->total_width is a
multiple of the compressed block size, presumably because it wouldn't
be possible to make an image that has a fraction of a block. However
it was doing this by aligning mt->total_width to align_w. Previously
align_w has been used as a shortcut for getting the block width
because before Gen9 the block width was always equal to the alignment.
Commit 4ab8d59a2 tried to fix these cases to use the block width
instead of the alignment but it missed this case.
I think in practice this probably won't make any difference because
the buffer for the texture will be allocated to be large enough to
contain the entire pitch and libdrm aligns the pitch to the tile width
anyway. However I think the patch is worth having to make the
intention clearer.

readpixels_can_use_memcpy will later call _mesa_format_matches_format_and_type
which does much tighter checks than these to decide if we can use
memcpy for readpixels.
Also, the checks do not seem to be extensive enough anyway, since we are
checking for signed/unsigned conversion only when the framebuffer has integers,
but the same checks could be done for other types anyway, since as long as
there is a signed/unsigned conversion we can't memcpy.
No regressions observed on i965/llvmpipe.

From Muchnick's Advanced Compiler Design and Implementation:
"To determine which variables are live at each point in a flowgraph, we
perform a backward data-flow analysis"
Previously, we were walking the blocks forwards and updating the livein and
then the liveout. However, the livein calculation depends on the liveout
and the liveout depends on the successor blocks. The net result is that it
takes one full iteration to go from liveout to livein and then another
full iteration to propagate to the predecessors. This works out to an
O(n^2) computation where n is the number of blocks. If we run things in
the other order, it's O(nl) where l is the maximum loop depth which is
practically bounded by 3.
In b2c6ba0c4b21391dc35018e1c8c4f7f7d8952bea, we made this same change in
the FS backend to great effect. Might as well keep it consistent and make
the same change for vec4. Also, this took the time to run the test:
ES31-CTS.arrays_of_arrays.InteractionFunctionCalls1
from 6:49.62 to 3:31.40 on Timothy Arceri's machine.

Commit b765119c changed the default value of all the counter bits to
64. However, older hardware only has 32 counter bits.
This has only been build-tested. We don't have any tests that verify
the advertised value against implementation behavior, so I don't know
what additional testing could be done.
NOTE: It appears that many Gallium drivers (at least r300 and i915g)
have the same problem, but I don't see a way for the state-tracker to
determine the counter size. Marek says, "For Gallium, a new PIPE_CAP or
new get_xxx_param function will be needed."
