nir/spirv: Simplify matrix loads/stores

Instead of handling all of the complexity at the end, we choose to
decorate types a bit more cleverly.  When we have a row-major matrix
type, we give it the stride of a single vector and give it's array
element type (which represents a column) the actual matrix stride.

Previously, we were using stop_at_matrix and handling everything from
matrix on down as special cases but now we walk the access chain all the
way to the end and then load.  Even though this looks like it may lead
to a significant functional change, it doesn't.  The reason why we
needed to do stop_at_matrix before was to handle row-major properly
since the offsets and strides would be all out-of-order.  Now that row
major matrix types have the small stride on the matrix and the large
stride on the vector, offsetting to a single column of a row-major
matrix works fine.  The load/store code simply picks up on the fact that
the stride isn't the type size and does multiple loads.  The generated
code from these methods should be the same.

points to a variable, we don't need the access chain at all.  Also,

st/mesa: release EGLImage on EGLImageTarget* error

The smapi->get_egl_image() call in st_egl_image_get_surface() stores a
reference to the EGLImage's texture in stimg.texture. That reference is
released via pipe_resource_reference(&stimg.texture, NULL) before stimg
goes out of scope at the end of the function, but not in the error path
if !is_format_supported().

ac/nir: fix 64-bit shifts

NIR always makes the shift amount 32 bits, but LLVM asserts if the two

happy.

ac/nir: implement 64-bit packing and unpacking

We implement the split opcodes, and tell NIR to lower the original ones.
The lowering to LLVM is a little more complicated, but NIR can optimize
the split ones a little better, and some NIR lowering passes that we
might want to use (particularly for doubles) emit the split ones.

This should fix pack/unpackDouble2x32, which seems like a bug since when
we enabled the Float64 capability. It will also fix pack/unpackInt2x32
when we enable the Int64 capability.

spirv: fix OpBitcast when the src and dst bitsize are different (v3)

Before, we were just implementing it with a move, which is incorrect
when the source and destination have different bitsizes. To implement
it properly, we need to use the 64-bit pack/unpack opcodes. Since
glslang uses OpBitcast to implement packInt2x32 and unpackInt2x32, this
should fix them on anv (and radv once we enable the int64 capability).

svga: don't call svga_texture_device_format_has_alpha() for PIPE_BUFFER

svga_texture_device_format_has_alpha() is only intended to work for
texture resources, not buffer resources.  This fixes a failed assertion
in the svga_texture() cast function when running texture buffer tests.

Also, add an assertion in svga_texture_device_format_has_alpha() to
catch the issue sooner.

svga: fix texture buffer object regression

With change 8aba778fa2cd98a0b5a7429d3c5057778a0c808c we stopped binding
sampler objects for texture buffers.  That broke our texture sample /
sampler view setup code.

Now, we loop over the max(num samplers, num sampler views) and handle
the sampler and view information separately.  For texture buffers,
the sampler will be NULL but the sampler view non-null.

svga: move assertion in draw_vgpu10()

svga: fix buffer binding flags initialization

If a buffer is created/initialized with glNamedBufferData we will
have no target (GL_ARRAY_BUFFER, GL_UNIFORM_BUFFER, etc) so the
svga_buffer::bind_flags will be zero until we try to get the buffer
handle.

This patch initializes the svga_buffer::bind_flags field when it's
zero.

This fixes the Piglit arb_uniform_buffer_object-rendering-dsa test.

Note that there's still issues in this area that'll have to be
addressed in the future.  For example, creating a buffer object
as GL_UNIFORM_BUFFER and later using it as a vertex buffer will
fail.
