We have been reconstructing/rematerializing uniforms for a while, but we
can do this in more scenarios, namely instructions which result is
immutable along the execution of a shader across all channels.
By doing this we gain the capacity to eliminate TMU spills which not
only are slower, but can also make us drop to a fallback compilation
strategy.
Shader-db results show a small increase in instruction counts caused
by us now being able to choose preferential compiler strategies that
are intended to reduce TMU latency. In some cases, we are now also
able to avoid dropping thread counts:

Bit 20 isn't actually MERGEDREGS, the mode for the entire geometry
pipeline is controlled by SP_VS_CTRL_REG0::MERGEDREGS and it appears to
be something preamble-related instead since writing any register in the
preamble hangs if it's set. This fixes those hangs on freedreno and
turnip since we no longer set it.

now that shaders are guaranteed to have a pointsize export, the only time

since 1.0 is used in nearly every case, drivers requiring this exporting
can avoid potential shader variants by adding a 1.0 export to the base
shader variant and the only using the ubo upload when pointsize is explicitly
set for wide point functionality
drivers can then be responsible for removing unused pointsize exports
as needed (or desired)

We don't need to restrict our timeout to 5 seconds, because the kernel's
hangcheck will ensure that the wait completes in finite time if the GPU
gets wedged. If the GPU is making progress, we don't want to time out
early and have pipe_transfer_map() return an error, causing glReadPixels()
to throw a confusing GL_OOM even though we're not out memory.
The INFINITE arg to this function isn't actually infinite, it's limited to
an hour. But an hour of GPU processing to wait on is probably plenty.
This 5s timeout has caused problems with the CTS on freedreno at high
parallelism, and I suspect is the cause of recent issues in the closed
traces replay jobs.

Here we remove the outer arrays on geom and tess shaders where
needed. Without this the pass can sometimes attempt to pack a
varying on only one side of the shader interface where it is not
actually needed. The result can be mismatching varying types.
