pan/bi: Introduce writemasks

I feel so dirty. But this will let the IR be a lot more flexible seeing
as we really are vector in a certain sense (I/O, small types)

pan/bi: Generalize swizzles to avoid extracts

We'd really rather not emit extracts. We are approaching on a vector IR
anyway which is annoying but really necessary to handle I/O and fp16
correctly. So let's just go all the way and deal with swizzles and masks
within reason; it'll still be somewhat saner in the long-term.

freedreno/ir3: try to avoid syncs

Update postsched to be better aware of where costly (ss) syncs would

freedreno/ir3: round-robin RA

In the second (scalar pass) use the information about # of registers
used in the first pass as the target max, and round-robin within that
range.  This generally gives the post-RA sched pass more opportunities
to re-order instructions to remove nop's.

Also, we can be a bit clever when assigning dest registers for SFU
instructions, by picking the register used for it's src (if available
and already assigned).  This avoids some (ss) syncs caused by write
after read hazards.  (Ie. the SFU instruction will read it's own src

intel/fs: Fix workaround for VxH indirect addressing bug under control flow.

The current workaround for this hardware bug involved marking the ADD
instruction used to initialize the address register as NoMask on
Gen12, which was based on the assumption that the problem was caused
by a hardware bug affecting the application of the execution mask to
the address register write.

However that doesn't seem to be the case: The address register write
was working correctly, the real problem leading to hangs on TGL is
that the indirect addressing logic is unable to deal with garbage
values in the address register (e.g. misaligned offsets), even for
channels which are currently inactive due to non-uniform control flow.
The current workaround isn't able to avoid that situation in general,
since the result of the NoMask ADD instruction for a dead channel is
calculated based on the corresponding (dead) component of the
indirect_byte_offset source, which would still be undefined in the
likely case that the source was initialized under control flow itself.

This would lead to hangs whenever MOV_INDIRECT was used under
non-uniform control flow in some scenarios like a tessellation shader
from GFXBench5/gl_4 (AKA Car Chase) on TGL.  In addition I've managed
to reproduce the same issue on earlier platforms by initializing the
whole address register with garbage before the ADD instruction, so
this seems to be a long-standing issue we have avoided mostly by luck.

This patch fixes the problem and applies the workaround to all
platforms, since even when the hardware is able to deal with garbage
address values without hanging there might be a significant
performance cost from reading random GRF registers due to the useless
extra EU cycles spent fetching registers for dead channels and due to
the potential for unintended serialization with respect to other
random instructions that could be executed in parallel, which may have
had a cost of the order of hundreds of cycles in the worst case
scenario.

egl/android: require ANDROID_native_fence_sync for buffer age

Querying buffer age requires a buffer to be dequeued.  But dequeuing
without ANDROID_native_fence_sync might imply eglClientWaitSync,
which results in a deadlock as the display lock is already held by
eglQuerySurface.
