The spirv-to-c-array.py script assembles a SPIR-V module,
then disassembles it, capturing that text, then re-assembles
that text, providing it on stdin. But this last invocation of
spirv-as must use '-' to specify that the text input appears
on stdin.

Currently it always errors out, complaining that there must
be exactly one input file.

d37bf148d2 nir/lower_blend: fix snorm factor clamping 
The spec says (emphasis mine):

  If the color attachment is fixed-point, the components of the source and
  destination values **AND BLEND FACTORS** are each clamped to [0,1] or [-1,1]
  respectively for an unsigned normalized or signed normalized color attachment
  prior to evaluating the blend operations. If the color attachment is
  floating-point, no clamping occurs.

However, neither the CTS nor any hardware implement this semantic.

For unsigned normalized formats, the definitions are roughly equivalent (except
perhaps around constant colours). 0 <= x <= 1 implies that 0 <= 1 - x <= 1.
Therefore if the source/destination colours are clamped to [0, 1], then their
complements are also in [0, 1], so clamping any blend factor (except constant
colour) has no effect if the source/dest were already clamped.

For signed normalized formats, however, this difference matters. -1 <= x <= 1
implies that 0 <= 1 - x <= 2... so to implement the spec text faithfully, we
would need to clamp again the complemented colour blend factors to return back
to signed normalized range. Software blending implementations can of course do
that... but doing so causes CTS fails, as the CTS reference renderer does not do
this.

This commit adjusts nir_lower_blend to match what actual hardware does, what CTS
requires, and what the spec should have said.

See https://gitlab.khronos.org/vulkan/vulkan/-/issues/4293 for the spec
resolution.
