We cannot guarantee that vertex buffers have the necessary alignment for
fetching all AoS members at once (for instance 4x32bit XYZW data). We can
however guarantee that for textures. This did not cause errors for older
llvm versions but it now matters and will cause segfaults if the data
happens to not be aligned. Thus we need to set alignment manually.
(Note that we can't actually really guarantee data to be even element aligned
due to offsets in vertex buffers being bytes and OpenGL allowing this, but
it does not matter for x86 as alignment is only required for sse vectors -
not sure what happens on other archs, however.)
This fixes https://bugs.freedesktop.org/show_bug.cgi?id=85467.
Not all drivers can set gl_Layer from VS. Add a fallback that passes the
instance id from VS to GS, and then uses the GS to set the layer.
Tested by adding
quad_buffers |= clear_buffers;
clear_buffers = 0;
to the st_Clear logic, and forcing set_vertex_shader_layered in all
cases. No piglit regressions (on piglits with 'clear' in the name).

DRI_PRIME setups have different issues due the lack of dma-buf fences
support in the drivers. For DRI3 DRI_PRIME, a race can appear, making
tearings visible, or worse showing older content than expected. Until
dma-buf fences are well supported (and by all drivers), an alternative
is to send the buffers to the server only when rendering has finished.
Since waiting the rendering has finished in the main thread has a
performance impact, this patch uses an additional thread to offload the
wait and the sending of the buffers to the server.

The sampler_array_size field was added by "mesa/st: add support for
dynamic sampler offsets". But the field wasn't getting copied in
the get_pixel_transfer_visitor() or get_bitmap_visitor() functions.
The count_resources() function then didn't properly compute the
glsl_to_tgsi_visitor::samplers_used bitmask. Then, we didn't declare
all the sampler registers in st_translate_program(). Finally, we
asserted when we tried to emit a tgsi ureg src register with File =
TGSI_FILE_UNDEFINED.
Add the missing assignments and some new assertions to catch the
invalid register sooner.

Using the asynchronous DMA engine for multi-dimensional operations seems

The DRM_IOCTL_MODE_CREATE_DUMB (and others) IOCTL isn't very rigorously
specified, which has the effect that some kernel drivers do not consider
the .pitch and .size fields of struct drm_mode_create_dumb outputs only.
Instead they will use these as lower bounds and overwrite them only if
the values that they compute are larger than what userspace provided.
This works if and only if userspace initializes the fields explicitly to
either 0 or some meaningful value. However, if userspace just leaves the
values uninitialized and the struct drm_mode_create_dumb is allocated on
the stack for example, the driver may try to overallocate buffers.
Fortunately most userspace does zero out the structure before passing it
to the IOCTL, but there are rare exceptions. Mesa is one of them. In an
attempt to rectify this situation, kernel drivers are being updated to
not use the .pitch and .size fields as inputs. However in order to fix
the issue with older kernels, make sure that Mesa always zeros out the
structure as well.
Future IOCTLs should be more rigorously defined so that structures can
be validated and IOCTLs rejected if output fields aren't set to zero.

This reverts commit 8d3f739383.
In the last commit we've updated our check to determine if the actual
code is buildable, rather than if the compiler acknowledges the option.
I.e. did anyone provide -mno-sse4.1 vs is my compiler too old.
Now this code will never be attemped to be build, in both cases.
Confirmed by building mesa with
export CFLAGS='-march=native -mno-sse4.1'

So when checking/building sse code we have three possibilities:
1 Old compiler, throws an error when using -msse*
2 New compiler, user disables sse* (-mno-sse*)
3 New compiler, user doesn't disable sse
The original code, added code for #1 but not #2. Later on we patched
around the lack of handling #2 by wrapping the code in __SSE4_1__.
Yet it lead to a missing/undefined symbol in case of #1 or #2, which
might cause an issue for #2 when using the i965 driver.
A bit later we "fixed" the undefined symbol by using #1, rather than
updating it to handle #2. With this commit we set things straight :)
To top it all up, conventions state that in case of conflicting
(-enable-foo -disable-foo) options, the latter one takes precedence.
Thus we need to make sure to prepend -msse4.1 to CFLAGS in our test.
