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.
