Kenneth Graunke	578f6a9534	glsl: Don't use MOD_TO_FRACT lowering on GLSL 1.30's % operator. ... MOD_TO_FRACT was designed to lower the GLSL 1.20 mod() function, which operates on floating point values. However, we also use ir_binop_mod for GLSL 1.30's % operator, which operates on integers. For now, make MOD_TO_FRACT only apply to floating-point mod operations. In the future, we may want to add a lowering pass for integer-based mod.
