b38d3cdcea nir/spirv/glsl450: increase asin(x) precision 
asin(x) is now implemented using a piecewise approximation, which
improves the precision for |x| < 0.5
Previously, we were using a polynomial approximation for both the
asin() and acos() functions. Unfortunately, for asin(), this polynomial
does not have enough precision to satisfy the Vulkan CTS requiremenents,
which define the asin() precision based on the precision of
atan2(x, sqrt(1.0 - x*x)). The piecewise approximation gives the needed
precision in the problematic range.

v2: Skip the piecewise approximation for acos

f1acf492de glsl: fix slow linking of uniforms in the nir linker 
Currently the nir linker resizes the amount of storage needed to hold
uniform information on the fly while linking. As shaders can contain
thousands of uniforms this can be very slow. For example some Godot
shaders can take 30 seconds to compile on some machines.

In this change we count the amount of storage needed before we start
processing the uniforms. This is what the GLSL IR linker does also.

f6214750eb glsl: stop cascading errors if process_parameters() fails 
Generally we do not completely stop compilation as soon as we see an error,
instead we continue on to attemp to find any futher errors.

This means we shouldn't be checking state->error to see if any error has
happened during the compilation process, doing so was causing
process_parameters() to fail on completely valid functions if there was
any error found in the shader previously. This then caused the valid
functions not to be found because the paramlist was considered empty,
resulting in the compiler spewing out misleading error messages.

Here we simply add the IR error value to the param list when we have
an issue with processing a parameter, this leads to much better error
messaging.

e91108691d nir: Fix sources for image atomic fadd 
Somehow we ended up with an extra scalar source up-front.  It doesn't
look like any drivers use this opcode yet so no real harm has been done
by it being wrong.

fcbc022787 nir: Add un/pack_32_4x8 opcodes 
Complement the existing un/pack_32_2x16 opcodes. These are useful for
8-bit format packing. On Midgard, they are equivalent to just a 32-bit
move, but other GPUs could lower to other packs if needed.
