On Broadwell and above, we have to use different MOCS settings to allow
the kernel to take over and disable caching when needed for external
buffers. On Broadwell, this is especially important because the kernel
can't disable eLLC so we have to do it in userspace. We very badly
don't want to do that on everything so we need separate MOCS for
external and internal BOs.
In order to do this, we add an anv-specific BO flag for "external" and
use that to distinguish between buffers which may be shared with other
processes and/or display and those which are entirely internal. That,
together with an anv_mocs_for_bo helper lets us choose the right MOCS
settings for each BO use.

The Vulkan 1.1.81 spec says:
"It is legal for offset.x + extent.width or offset.y + extent.height
to exceed the dimensions of the framebuffer - the scissor test still
applies as defined above. Rasterization does not produce fragments
outside of the framebuffer, so such fragments never have the scissor
test performed on them."
Elsewhere, the Vulkan 1.1.81 spec says:
"The application must ensure (using scissor if necessary) that all
rendering is contained within the render area, otherwise the pixels
outside of the render area become undefined and shader side effects
may occur for fragments outside the render area. The render area
must be contained within the framebuffer dimensions."
Unfortunately, there's some room for interpretation here as to what the
consequences are of having the render area set to exactly the
framebuffer dimensions and having a scissor that is larger than the
framebuffer. Given that GL and other APIs provide automatic clipping to
the framebuffer, it makes sense that applications would assume that
Vulkan does this as well. It costs us very little to play it safe and
just clamp client-provided scissors to the framebuffer dimensions.
Fortunately, the user is required to provide us with at least one
scissor so we don't need to handle the case where they don't.

This is the second patch needed to fix the following piglit tests:
tests/spec/arb_gl_spirv/linker/uniform/multisampler.shader_test
tests/spec/arb_gl_spirv/linker/uniform/multisampler-array.shader_test
Although in this case it doesn't affect so many borrowed tests, as
there aren't too many tests using multisamplers on Intel.
It is worth to note that this patch is also needed when those tests
are run on GLSL mode (using the --glsl option). Although most Intel
drivers would not be able to run/execute tests using multisamplers, as
GL_MAX_IMAGE_SAMPLES is zero, technically those tests are expected to
link correctly, so linking tests should pass.

removing unused local variables at the end of the optimization loop.
