util: Make CLAMP turn NaN into MIN.

The previous implementation of CLAMP() allowed NaN to pass through
unscathed, by failing both comparisons.  NaN isn't exactly a value
between MIN and MAX, which can break the assumptions of many callers.

This patch changes CLAMP to convert NaN to MIN, arbitrarily.  Callers
that need NaN to be handled in a specific manner should probably open
code something, or use a macro specifically designed to do that.

Section 2.3.4.1 of the OpenGL 4.5 spec says:

   "Any representable floating-point value is legal as input to a GL
    command that requires floating-point data. The result of providing a
    value that is not a floating-point number to such a command is
    unspecified, but must not lead to GL interruption or termination.
    In IEEE arithmetic, for example, providing a negative zero or a
    denormalized number to a GL command yields predictable results,
    while providing a NaN or an infinity yields unspecified results."

While CLAMP may apply to more than just GL inputs, it seems reasonable
to follow those rules, and allow MIN as an "unspecified result".

This prevents assertion failures in i965 when running the games
"XCOM: Enemy Unknown" and "XCOM: Enemy Within", which call

   glTexEnv(GL_TEXTURE_FILTER_CONTROL_EXT, GL_TEXTURE_LOD_BIAS_EXT,
            -nan(0x7ffff3));

presumably unintentionally.  i965 clamps the LOD bias to be in range,
and asserts that it's in the proper range when converting to fixed
point.  NaN is not, so it crashed.  We'd like to at least avoid that.

gbm: Remove is_planar_format dead code

This was only used in create_dumb() to blacklist planar formats.
However, the start of the function already whitelists ARGB8888 (cursor)
and XRGB8888 (scanout), and nothing else. So this entire function can be
removed.

gbm: Check harder for supported formats

Luckily no-one really used the is_format_supported() call, because it
only supported three formats.

Also, since buffers with alpha can be displayed on planes, stop banning
them from use.

gbm: Axe buffer import format conversion table

Wayland buffers coming from wl_drm use the WL_DRM_FORMAT_* enums, which
are identical to GBM_FORMAT_*. Similarly, FD imports do not need to
convert between GBM and DRI FourCC, since they are (almost) completely
compatible.

This widens the formats accepted by gbm_bo_import() when importing
wl_buffers; previously, only XRGB8888, ARGB8888, RGB565 and YUYV were
supported.

i965/gen4: Set tile offsets to zero after depth rebase

Current logic calls intel_renderbuffer_set_draw_offset() which in
turn tries to calculate x and y offset against layer/level settings
that are against the original miptree actually having sufficient
levels/layers. This returns correctly x=0 y=0 regardless of the given
layer/level only because one calls intel_miptree_get_image_offset()
which goes and consults miptree offset table which in turn luckily
contains entries for max-mipmap levels, all initialised to zero even
in case of non-mipmapped.

This patch stops consulting the table and simply sets the draw
offsets to zero that are compatible with the single slice miptree
backing the renderbuffer.
This prepares for ISL based miptrees that calculate offsets
on-demand and do not tolerate levels beyond what the miptree has.

i965/miptree: Do not rely on msaa type to decide if aux is needed

Once the driver moves to ISL both compressed and uncompressed have
the same type. One needs to tell them apart by other means. This
can be done by checking the existence of mcs_buf.

There is a short period of time within intel_miptree_create()
where mcs_buf doesn't exist yet (between calls to
intel_miptree_create_layout() and intel_miptree_alloc_mcs()).
First compute_msaa_layout() makes the decision if compression is
to be used and sets the msaa_layout type. Then based on the type
one sets aux_usage and finally decides if mcs_buf is needed.

This patch duplicates the logic in compute_msaa_layout() and uses
that to make the decision on aux_usage and mcs_buf allocation.
Most of the original logic in compute_msaa_layout() will be gone
in later patch leaving only one version.

Elsewhere only brw_populate_sampler_prog_key_data() needs to know
if compression is used based on the msaa_type. This is now
replaced with consideration for number of samples and existence
of mcs_buf. All other occurrences consider CMS || UMS which can
be represented using single the type of ISL_MSAA_LAYOUT_ARRAY
without any tweaks.
