llvmpipe: improve alignment calculation for fetching/storing pixels
This was always doing per-pixel alignment which isn't necessary, except
for the buffer case (due to the per-element offset). The disabled code
for calculating it was incorrect because it assumed that always the full
block would be fetched, which may not be the case, so fix this up.
The original code failed for instance for r10g10b10a2 the alignment would
have been calculated as 4 (block_width) * 4 (bytes) so 16, but the actual
fetch may have only fetched 2 values at a time, hence only alignment 8 -
it is unclear what exactly would happen in this case (alignment larger
than size to fetch).

llvmpipe: reduce alignment requirement for 1d resources from 4x4 to 4x1
For rendering to buffers, we cannot have any y alignment.
So make sure that tile clear commands only clear up to the fb width/height,
not more (do this for all resources actually as clearing more seems
pointless for other resources too). For the jit fs function, skip execution
of the lower half of the fragment shader for the 4x4 stamp completely,
for depth/stencil only load/store the values from the first row
(replace other row with undef).
For the blend function, also only load half the values from fs output,
replace the rest with undefs so that everything still operates on the
full 4x4 block to keep code the same between 4x1 and 4x4 (except for
load/store of course which also needs to skip (store) or replace these
values with undefs (load))., at the cost of slightly less optimal code
being produced in some cases.
Also reduce 1d and 1d array alignment too, because they can be handled the
same as buffers so don't need to waste memory.
v2: don't try to run special blend code for 4x1, (very) slightly less
complexity if we just use the same code as for 4x4 which may or may not
make it easier to optimize in the future (as we care a lot more about 4x4
performance than 1d).

apparently can trigger a bug in llvm.

045612c (intel: Add an assert for glCopyTexSubImage() being

to make sure that multisampling was not in use, based on the
assumption that glCopyTexSubImage() can't legally be used with
multisampling.
However, there is one case where glCopyTexSubImage() can legally be
used with multisampling: when the source buffer is a multisampled
window system buffer. If the source and destination color formats
don't match, the blorp path will fail, so intel_copy_texsubimage()
will be called. In this case, we need intel_copy_texsubimage() to
return false so that we fall back to meta to do the copy. (The
multisampled source buffer won't cause a problem for the meta path,
because it uses glReadPixels, which forces a multisample resolve).
It's still safe to assert that the destination image is
single-sampled, because it's not legal to call glCopyTexSubImage() on
multisampled textures.

gallivm: fix out-of-bounds access with mirror_clamp_to_edge address mode
Surprising this bug survived so long, we were missing a clamp (in the
linear filtering version).
(Valgrind complained a lot about invalid reads with piglit texwrap,
I've also seen spurios failures in this test which might have
happened due to this. Valgrind probably didn't complain before the
alignment reduction in llvmpipe to 4x4 since the test is using tiny
textures so the reads were still always well within allocated area.)
While here, also do an effective clamp (after half subtraction)
of [0,length-0.5] instead of [0, length-1] which saves an instruction
(the filtering weight could be different due to this, but only if
both texels point to the same max texel so it doesn't matter).

llvmpipe: reduce alignment requirement for resources from 64x64 to 4x4
The overallocation was very bad especially for things like 1d array
textures which got blown up by a factor of 64. (Even ordinary smallish
2d textures benefit a lot from this, a mipmapped 64x64 rgba8 texture
previously used 7*16kB = 112kB instead of now ~22kB.)
4x4 is chosen because this is the size the jit functions run on, so
making it smaller is going to be a bit more complicated.
It is actually not strictly 4x4 pixel, since we'd want to avoid situations
where different threads are rendering to the same cacheline so we keep
cacheline size alignment in x direction (often 64bytes).
To make this work introduce new task width/height parameters and make
sure clears don't clear the whole tile if it's a partial tile. Likewise,
the rasterizer may produce fragments outside the 4x4 blocks present in a
tile, so don't call the jit function for them.
This does not yet fix rendering to buffers (which cannot have any y
alignment at all), and 1d/1d array textures are still overallocated by a
factor of 4.
v2: replace magic number 4 with LP_RASTER_BLOCK_SIZE, fix size of buffers
allocated (needed in case we render to them).

- Use float registers to scale and offset texture coordinates.
- Change offset computation to consider float coordinates.
- Round the scaled coordinates down to nearest integer.
- Modify src texture coordinates clipping to account for scaling..

Pre-Haswell hardware doesn't support an arbitrary restart index, and
instead compares the index buffer value against 0xFF for byte-size

OpenGL allows the restart index to be an arbitrary unsigned integer.
When comparing against byte/short types, the index buffer value should
be promoted to a full 32-bit integer before doing the comparison. The
restart index is /not/ supposed to be masked to byte/short size.
This means that with certain restart indexes, the comparison should
always fail. For example, a restart index of 0xF000FFFF should never
match any byte/short index buffer values due to the extra high bits.
We must not enable hardware primitive restart in such a case. For now,

i965/fs: Fix segfault in instruction scheduling with LINTERP using last GRF.
The scheduler didn't know about uniform-type accesses, and if a uniform
access was last in a 16-wide, we'd walk off the end of the array. This
never happened, because we'd never coalesce out all the GRFs, due to a bug
to be fixed in the next commit.

mesa: Fix test for optimistic coloring being necessary.
i965 and radeon use ra_set_node_reg() to force payload registers to
specific registers while exposing those registers to the allocator still.
We were treating those register nodes as unsuccessfully allocated in the
ra_simplify() step, leading to walking the registers again to do
optimistic coloring even if there was nothing left ot do.

gallium: fix build on uclibc system
execinfo.h and debug_symbol_name_glibc() are pure GNU-isms and do not
build on uclibc systems. A previous patch addressed this issue, but
there was an error. This patch corrects that error. See

intel: Enable blit glCopyTexSubImage/glBlitFramebuffer with sRGB.
Since the introduction of default-to-SARGB8 window system framebuffers,
non-blorp hardware lost blit acceleration for these two paths between the
window system and ARGB8888 textures. Since we shouldn't be doing any
conversion anyway, just compatibility-check the linear variants of the
formats.
