The fixed alignment of u_upload_mgr will go away.
This is the first step.
The motivation is that one u_upload_mgr can have multiple users,
each allocating from the same buffer, but requiring a different alignment.

The function only aligned the size, but not the offset.
The offset was aligned only when the previous suballocation was aligned.
That yielded the correct offset alignment if the alignment was constant
for all suballocations.
Instead, directly align the offset, but allow an unaligned size.
There is no change in behavior, because the alignment is constant
at the moment.
This a prerequisite for allowing a variable alignment for suballocations.

First off, we can't flush in the middle of a command. Secondly
requesting the extra push space might cause a flush to happen. If that
flush happens, we'd have to do the PUSH_REFN again. So instead do
PUSH_REFN after the push space request. This helps avoid rare crashes
with supertuxkart in libdrm due to assertion failures.

When Connor originally drafted NIR, he copied the same function+overload
system that GLSL IR had with a few names changed. However, this
double-indirection is not really needed and has only served to confuse
people. Instead, let's just have functions which may not have unique names
and may or may not have an implementation. If someone wants to do overload
resolving, they can hav a hash table based function+overload system in the
overload resolving pass. There's no good reason to keep it in core NIR.

Tessellation control shaders need to be careful when writing outputs.
Because multiple threads can concurrently write the same output
variables, we need to only write the exact components we were told.
Traditionally, for sub-vector writes, we've read the whole vector,
updated the temporary, and written the whole vector back. This breaks
down with concurrent access.
This patch prepares the way for a solution by adding a writemask field
to store_var intrinsics, as well as the other store intrinsics. It then
updates all produces to emit a writemask of "all channels enabled". It
updates nir_lower_io to copy the writemask to output store intrinsics.
Finally, it updates nir_lower_vars_to_ssa to handle partial writemasks
by doing a read-modify-write cycle (which is safe, because local
variables are specific to a single thread).
This should have no functional change, since no one actually emits
partial writemasks yet.
v2: Make nir_validate momentarily assert that writemasks cover the
complete value - we shouldn't have partial writemasks yet
(requested by Jason Ekstrand).
v3: Fix accidental SSBO change that arose from merge conflicts.
v4: Don't try to handle writemasks in ir3_compiler_nir - my code
for indirects was likely wrong, and TTN doesn't generate partial
writemasks today anyway. Change them to asserts as requested by
Rob Clark.

This is a rewrite of vc4_opt_qpu_schedule.c to operate on QIR. Texture
fetch can probably take as much as the rest of the cycles of the program,
so it's important to hide our other cycles during it (which is hard to do
after register allocation). Also, we can queue up multiple texture
requests before collecting the resulting samples, so that we keep the
texture unit busy more of the time.
High-settings openarena performance +2.35849% +/- 0.221154% (n=7). Also
about 2-3% on the multiarb demo. 8 piglit tests
(ext_framebuffer_multisample accuracy depthstencil) go from failing in
rendering to failing in register allocation, but hopefully I can fix that
up with some better register pressure handling here.

Those stages only really work for OGL-style texturing (so number of samplers
and views mostly the same, certainly for the max values).
These get often set up all at once, thus there might be max number of both
even if all of them are just NULL. We must not set the max number of samplers
and views to the same value since that will lead to terrible things if a driver
supports more views than samplers (and the state tracker set up all the views).
(This will not make these stages magically work if a shader uses dx10-style
texturing, they might still replace an actually used sview in that case.)
