prog_to_nir: Make RSQ properly take the absolute value of its argument.
I just botched this when writing the original code.
From the ARB_vertex_program specification:
"The RSQ instruction approximates the reciprocal of the square root of
the absolute value of the scalar operand and replicates it to all four
components of the result vector."
Fixes a Glean vertProg1 subtest:
RSQ test 2 (reciprocal square root of negative value)
