glsl: add support for complie-time constant expressions
This patch replaces the old interger constant qualifiers with either the new ast_layout_expression type if the qualifier requires merging or ast_expression if the qualifier can't have mulitple declarations or if all but the newest qualifier is simply ignored. We also update the process_qualifier_constant() helper to be similar to the one in the ast_layout_expression class, but in this case it will be used to process the ast_expression qualifiers. Global shader layout qualifier validation is moved out of the parser in this change as we now need to evaluate any constant expression before doing the validation.
