according to KHR_gl_texture_3D_image:
If <target> is EGL_GL_TEXTURE_3D_KHR, <buffer> must be the name of a
complete, nonzero, GL_TEXTURE_3D (or equivalent in GL extensions) target
texture object, cast
into the type EGLClientBuffer. <attr_list> should specify the mipmap
level (EGL_GL_TEXTURE_LEVEL_KHR) and z-offset (EGL_GL_TEXTURE_ZOFFSET_KHR)
which will be used as the EGLImage source; the specified mipmap level must
be part of <buffer>, and the specified z-offset must be smaller than the
depth of the specified mipmap level.
thus a 2d view of a 3d surface is not only legal, it's part of the spec and
must be supported when available

When CCS compression first came out on Skylake, we referred to it as
"renderbuffer compression", or RBC for short. However, that name has
long since fallen out of favor, and we refer to it as CCS nearly
everywhere.
This patch renames DEBUG_NO_RBC to DEBUG_NO_CCS inside the codebase
for clarity, and adds INTEL_DEBUG=noccs. The legacy INTEL_DEBUG=norbc
name continues to work, because it's one line of code and having both
names makes our lives easier in the interim.

The sampler can only decode ASTC surfaces that are Y-tiled. ISL has
been asserting this restriction at surface creation time.
However, some drivers want to create a surface that is only used for
copying compressed data. And during the copy, the surface won't have a
compressed format.
To enable this behavior, we choose to move the tiling assertion to the
moment a surface state is created for the sampler.

INTEL_DEBUG is defined (since 4015e1876a) as:
#define INTEL_DEBUG __builtin_expect(intel_debug, 0)
which unfortunately chops off upper 32 bits from intel_debug
on platforms where sizeof(long) != sizeof(uint64_t) because
__builtin_expect is defined only for the long type.
Fix this by changing the definition of INTEL_DEBUG to be function-like
macro with "flags" argument. New definition returns 0 or 1 when
any of the flags match.
Most of the changes in this commit were generated using:
