There was a security problem with some `gitlab_gql.py` scenarios because
of `\r` and `\n` in the token file, which interrupted the requests for
Gitlab endpoints.
Stripping the token file after reading the file content solves the
problem.

...Rather than reserving the union of the registers live-out of the
predecessors. This avoids reserving registers that are killed along a
control flow edge (where the predecessor has another successor that does
use the register).

This means we don't reserve the registers, which improves RA
considerably. Using a special preload psuedo-op instead of a regular
move allows us to constrain semantics and gaurantee coalescing.

This makes the dataflow easier to read, especially with splits and

We know that phi nodes are always at the start (this is asserted in
agx_validate and a fundamental invariant of SSA form). That means we can
cheaply iterate all n phi nodes forward (or n non-phi nodes backwards)
in O(n) time. We already open code this idiom in a few places, use
common iterators instead so we don't need to justify in random places.

this ensures there's no weird perf happening, avoids using renderpass
instead of dynamic rendering, and avoids hitting an assert from broken
framebuffer construction

Setting the NIR options takes care of iris thanks to the common st/mesa
linking code, and updating brw_nir_link_shaders should handle anv.
The main effort here is updating remap_tess_levels, which needs to
handle vector stores, writemasking, and swizzling. Unfortunately,
we also need to continue handling the existing single-component
access because it's used for TES inputs, which we don't vectorize.
We could try to vectorize TES inputs too, but they're all pushed
anyway, so it wouldn't buy us much other than deleting this code.
Also, we do have opt_combine_stores, but not one for loads.
One limitation of using nir_vectorize_tess_levels is that it works
on variables, and so isn't able to combine outer/inner writes that
happen to live in the same vec4 slot (for triangle domains). That
said, it's still better than before.
For writes, we allow the intrinsics to supply up to the full size
of the variable (vec4 for outer, vec2 for inner) even if the domain
only requires a subset of those components (i.e. triangles needs 3).
