If an application calls eglMakeCurrent with the same context and the same
draw and read surfaces as the current ones, there is no need to go
through all the work of unbinding/flushing the old context and binding
the new one.
While the EGL spec is a bit ambiguous here, it seems that the implicit
flush of the outgoing context only needs to be done when the context is
actually changed.

The flush of the outgoing GL context, as required by the EGL spec for
eglMakeCurrent and extended by KHR_context_flush_control, is already
performed in the unbindContext call. There is no need to pierce through
the layers and unconditionally call glFlush() here.
Getting the out-fence FD for explicit fencing needs to move behind the
unbindContext, to make sure we are getting the fence for the most
recently flushed commands.

Doing this for ir3 required adding a struct for limits of how much base to
fold in (which NTT wants as well for its case of shared vars), otherwise
the later work to lower to the 1<<9 word limit would emit more
instructions.
The shader-db results are that sometimes the reduction in NIR instruction
count results in the fewer sampler prefetches due to the shader being
estimated to be shorter (dota2, nexuiz):
total instructions in shared programs: 8996651 -> 8996776 (<.01%)
total cat5 in shared programs: 86561 -> 86577 (0.02%)

Lower to `sample_mask = 0`. Actually that implements a demote... doing
discard correctly probably requires rewriting the shader control flow to
insert a return where necessary...
Also, possibly we should be lowering this in NIR to play nice with
gl_SampleMask writes but that's a problem for when we understand the
hardware better.

According to RFC 4189 CSV files should be encoded using CRLF newlines,
not LF. This helps compatibility with tools, like python's csv module,
who always uses CRLF.
While we're at it, normalize the one CSV that was CRLF in-repo to LF,
and let git do the newline-normalization when needed instead.

By software ABI, a blend shader is permitted to clobber registers
R0-R15. The scheduler needs to be aware of this, to avoid moving a write
to one of these registers past the BLEND itself. Otherwise the schedule
is invalid.
This bug affects GLES3.0, but is rare enough in practice that we had
missed it. It requires a fragment shader to write to multiple render
targets with attached blend shaders, and have temporaries register
allocated to R0-R15 that are not read by the blend shader, but are sunk
past the BLEND instruction by the scheduler. Prevents a regression when
switching boolean representations on:

Although Bifrost clause packing and register assignment is tricky, the
relevant code is by now extensively tested, and there's no remaining
reverse-engineering here. So disassembling verbosely just adds tons of
noise to pandecode without increasing the useful information.

It's a pointer to a thread storage descriptor, not a framebuffer
descriptor. Unlike Midgard, these don't have to alias. The FBD pointer
was unused anyway, so remove it to reduce noise in pandecode dumps.

Rather than emulating page tables, poorly, with a hash table, use a
red-black tree and store the intervals directly. This is deterministic
instead of probabilistic, attaining O(log n) performance for n mapped
intervals which is good enough. Unlike the hash table approach, this
allows us to iterate intervals easily.

The switch statement in anv_descriptor_data_for_type() shows that this
field isn't used on SKL+.
On XeHP, this avoids assert failures by preventing
isl_surf_fill_image_param() from being called. That function doesn't
expect Tile4 surfaces.
