With NGG culling, the shaders are split into two parts:
the top part that computes just the position output,
and the bottom part which produces the other outputs.
To reduce redundancy between the two, I added some code
to reuse uniform variables between them. However, there is
an edge case I didn't think about: because of vertex repacking,
it is possible for the bottom part to process a different vertex.
Therefore it can take a different divergent code path
(though it must still take the same uniform code path).
Due to this, when a uniform value comes from divergent control
flow, this may be undefined in the bottom part.
This commit stops reusing uniform variables from
divergent control flow, to fix issues that arise from this.

Oh, the irony. I linked to this file in a software design class as an
example of how unit testing works under the hood, since it's not using
any particular testing framework. In doing so I realized the test is
totally broken. It doesn't matter -- the tests passed before, pass now,
and the code being tested is correct. But let's still fix the
embarassing logic error for future Panfrost hackers.

It is really small, and used just twice, so we just call qpu_magic.
We also update how it is used:
* QFILE_NULL is an undef so we can just load anything. Previously we
were using accumulator 0, but there isn't any real reason to use
an accumulator for this. Using reg 0.
* QFILE_LOAD_IMM: it seems that we don't use at all right now, so
let's add an assert

This is boilerplate that drivers have to replicate, so make a nice helper.
The feature/property macro lists are are copy and pasted from anv, though
the helper functions has been split between 1.1 and 1.2 (and thus the macros
