Kenneth Graunke	807e967c61	glsl: Use ir_rvalue to represent generic error_type values. ... Currently, ir_call can be used as either a statement (for void functions) or a value (for non-void functions). This is rather awkward, as it's the only class that can be used in both forms. A number of places use ir_call::get_error_instruction() to construct a generic value of error_type. If ir_call is to become a statement, it can no longer serve this purpose. Unfortunately, none of our classes are particularly well suited for this, and creating a new one would be rather aggrandizing. So, this patch introduces ir_rvalue::error_value(), a static method that creates an instance of the base class, ir_rvalue. This has the nice property that you can't accidentally try and access uninitialized fields (as it doesn't have any). The downside is that the base class is no longer abstract.
