pan/mdg: refactor emit_alu_bundle

This refactor prepares emit_alu_bundle() for the next commit that
reconstructs branch instructions right before emission.
It also simplifies the code since the previous control flow was only
better when we had the prepacked fields in midgard_instruction.

pan/mdg: remove ins->alu

This commit removes the `ins->alu` field from midgard_instruction,
simplifying the code by just recreating midgard_vector_alu later when we
have to emit it.

This effectively reverts part of 2907faee, which changed dri2_make_current() to
always take a dri2_dpy reference regardless of whether or not a new context or
surface(s) were being bound. This led to a reference count imbalance as there
was no corresponding code added to drop a reference on the dri2_dpy. As a
consequence, any application that called eglInitialize() on a default/native
display after having called eglTerminate() would always get back the old
dri2_dpy, inheriting its previous state.

As the reference count is there to prevent the dri2_dpy from being destroyed
between eglTerminate() and eglInitialize() calls when a context is still bound,
a reference should only be taken when a successful call to
dri2_dpy->core->bindContext() has been made. Fix the issue by restoring the old
reference counting behaviour.

iris: Delete shader variants when deleting the API-facing shader

We were space-leaking iris_compiled_shader objects, leaving them around
basically forever - long after the associated iris_uncompiled_shader was
deleted.  Perhaps even more importantly, this left the BO containing the
assembly referenced, meaning those were never reclaimed either.  For
long running applications, this can leak quite a bit of memory.

Now, when freeing iris_uncompiled_shader, we hunt down any associated
iris_compiled_shader objects and pitch those (and their BO) as well.

One issue is that the shader variants can still be bound, because we
haven't done a draw that updates the compiled shaders yet.  This can
cause issues because state changes want to look at the old program to
know what to flag dirty.  It's a bit tricky to get right, so instead
we defer variant deletion until the shaders are properly unbound, by
stashing them on a "dead" list and tidying that each time we try and
delete some shader variants.

This ensures long running programs delete their shaders eventually.

nir: Use a single list for all shader variables

Instead of having separate lists of variables, roughly sorted by mode,
use a single list for all shader-level NIR variables.  This makes a few
list walks a bit longer here and there but list walks aren't a very
common thing in NIR at all.  On the other hand, it makes a lot of things
like validation, printing, etc. way simpler.  Also, there are a number
of cases where we move variables from inputs/outputs to globals and this
makes it way easier because we no longer have to move them between
lists.  We only have to deal with that if moving them from the shader to
a nir_function_impl.
