glsl2: Remove the shader_in/shader_out tracking separate from var->mode.
I introduced this for ir_dead_code to distinguish function parameter outvals from varying outputs. Only, since ast_to_hir's current_function is unset when setting up function parameters (they're needed for making the function signature in the first place), all function parameter outvals were marked as shader outputs anyway. This meant that an inlined function's cloned outval was marked as a shader output and couldn't be dead-code eliminated. Instead, since ir_dead_code doesn't even look at function parameters, just use var->mode. The longest Mesa IR coming out of ir_to_mesa for Yo Frankie drops from 725 instructions to 636.
