In a fragment shader, r0 is written out with a special branch sequence.
r0 is not a real register here, but essentially a pipeline register --
as such, it needs to be written out in full and on time, with hanging
dependencies in the bundle. Otherwise, we break up the bundle, which
costs an extra ALU cycle and adds a move.
When the scheduler ran last thing, we could do this analysis within the
scheduler. Now that RA can run after scheduling, that's no longer valid,
so we remove the analysis and always break it up (at a performance
penalty). Future work can add a post-RA/post-schedule pass to merge
writeout blocks if possible. It's a bit of a low-priority next to fixing
conformance regressions, of course.

Certain ops that only take one argument have an imaginary "zero"
constant for their second argument. For instance, conversions:
i2f [dest], [source], #0
Memory corruption meant that #0 was instead random noise. For some ops,
that doesn't matter (manifested as abnormally large code size and poor
scheduling due to extra constants in random places). But for others,
where a 1-op is emulated by a 2-op with an implicit 0 second argument,
that broke things.
Fixes iabs (emulated by iabsdiff).

This new 'platform' is added by default with no guards.
It is effectively a copy of the surfaceless one, with updated function
names and brand new probe function.
Due to the reuse, some of the ifdef HAVE_SURFACELESS_PLATFORM guards
have been dropped.
A worthy mention are the changes in _egFindDisplay, since the original
and dup'd fd are required, we make use of the plat_opt argument.
Note that no hacks for eglGetDisplay are added - the API works only with
the eglGetPlatformDisplay* API.
v2:
- s/_eglCompareDeviceDisplay/_eglSameDeviceDisplay/ (Eric)
- let ^^ return bool (Eric)
- fixup meson build, move files() further up (Eric)
- copy from plat. surfaceless w/o the visual cleanups
- close and free when destroying the dpy
- sprinkle a few _eglDeviceSupports
- split fd handling into separate function
- use directly the render node if no FD is given (Mathias)
v3:
- s/dpy/disp/g
- drop swap_buffers* callbacks
- drop loader_set_logger()
- drop local define
- re-introduce _eglGetDRMDeviceRenderNode()
- EGL_WARN on ForceSoftware with HW device - continue using the HW device
- bail out for "EGL_MESA_device_software" until it's fixed
- wire-up the Android build
v4:
- use new style _eglFindDisplay()
- split hw vs sw code paths
- don't close the internal fd (already handled in FiniDisplay())
- make swrast work (bit hacky bit will do for now)
- Android for real, drop autotools
- Correct HW + LIBGL_ALWAYS_SOFTWARE check
- use the dri2_create_drawable() helper
v5:
- enhance comment around fd checks (Mathias)
- rebase for dri2_init_surface() changes

A previous optimization converts fmax(x, 0.0) instructions to fmov.pos.
This pass then propagates the .pos from the move up to the source
instruction (when possible). From there, copy propagation will eliminate
the move.

for saturate, as Bifrost can also benefit.

This prepass, run after scheduling but before RA, specializes to
pipeline registers where possible. It walks the IR, checking whether
sources are ever used outside of the immediate bundle in which they are
written. If they are not, they are rewritten to a pipeline register (r24
or r25), valid only within the bundle itself. This has theoretical
benefits for power consumption and register pressure (and performance by
extension). While this is tested to work, it's not clear how much of a
win it really is, especially without an out-of-order scheduler (yet!).
