b33f811068 glsl: fix incorrect optimisation in opt_constant_variable() 
When handling function inputs the optimisation pass incorrectly
assumes the inputs are undefined. Here we simply change things to
assume inputs have always been assigned a value. Any further
optimisations will be taken care of once function inlining takes
place.

Closes: https://gitlab.freedesktop.org/mesa/mesa/-/issues/2984
Fixes: 65122e9e80 ("ir_constant_variable: New pass to mark constant-assigned variables constant.")

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
