glsl: Add ir_binop_vector_extract
The new opcode is used to get a single field from a vector. The field index may not be constant. This will eventually replace ir_dereference_array of vectors. This is similar to the extractelement instruction in LLVM IR. http://llvm.org/docs/LangRef.html#extractelement-instruction v2: Convert tabs to spaces. Suggested by Eric. v3: Add array index range checking to ir_binop_vector_extract constant expression handling. Suggested by Ken. v4: Use CLAMP instead of MIN2(MAX2()). Suggested by Ken.
