845e2b3954 nir/opt_algebraic_tests: Remove unnecessary input_count.
Originally this was for sizing the array, but now we're doing std::vector.

363b2655b6 nir: Add a unit test base class for algebraic patterns
nir_algebraic_pattern_test can validate shaders with the following
structure:

%0 = @provide(base = 0)
...
%N = @provide(base = input_count)

// multiple equivalent expressions
a = ...
b = ...

valid = ieq(a, b)
@use(valid)

Expressions are evaluated by emulating the shader using
nir_eval_const_opcode.
