egl: Add MKDIR_GEN definition

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.

nir: Use nir_src_copy instead of direct assignments.

If the source is an indirect register, there is ralloc'd data.  Copying
with a direct assignment will copy the pointer, but the data will still
belong to the old instruction's memory context.  Since we're lowering
and throwing away instructions, that could free the data by mistake.

Instead, use nir_src_copy, which properly handles this.

This is admittedly not a common case, so I think the bug is real,
but unlikely to be hit.

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

Current logic calls intel_renderbuffer_set_draw_offset() which in

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

i965: Check if the modifier is supported in select_best_modifier

Otherwise, if a client gave us a list of modifiers that contained a
modifier we understand but which is not supported on the hardware, we
might return that one and then fail to create the image.

i965/miptree: Allocate HiZ up-front

HiZ, like MCS and CCS_E, can compress more than just clear colors so we
want it turned on whenever the miptree is being used as a depth
attachment.  It's theoretically possible for someone to create a depth
texture, upload data with glTexSubImage2D, and texture from it without
ever binding it as a depth target.  If this happens, we would end up
wasting a bit of space by allocating a HiZ surface we never use.
However, this is rather unlikely out side of test cases, so we're better
off just allocating it up-front.

i965/miptree: Add an intel_tiling_supports_hiz helper

We need this split for the same reason that we need the split for CCS:
intel_miptree_supports_hiz is called *before* we choose the actual
tiling.  Adding a tiling_supports_hiz helper lets choose_aux_usage
more accurately decide whether or not to enable hiz.  In particular,
this prevents us from enabling HiZ on linear depth buffers.

util/u_queue: add an option to resize the queue when it's full

Consider the following situation:

  do_something();
  util_queue_add_job(...);
  mtx_unlock(mutex);

If the queue is full, util_queue_add_job will wait for a free slot.
If the job which is currently being executed tries to lock the mutex,
it will be stuck forever, because util_queue_add_job is stuck.

The deadlock can be trivially resolved by increasing the queue size
(reallocating the queue) in util_queue_add_job if the queue is full.
Then util_queue_add_job becomes wait-free.
