Now that all the places that used to generate array derefeneces of
vectors have been changed to generate either ir_binop_vector_extract or
ir_triop_vector_insert (or both), remove all support for dealing with
this deprecated construct.
As an added safeguard, modify ir_validate to reject ir_dereference_array
of a vector.
v2: Convert tabs to spaces. Suggested by Eric.

Lower ir_binop_vector_extract with a constant index to a swizzle. This
is exactly like ir_dereference_array of a vector with a constant index.
v2: Convert tabs to spaces. Suggested by Eric.
v3: Correctly call convert_vector_extract_to_swizzle in
ir_vec_index_to_swizzle_visitor::visit_enter(ir_call *ir). Suggested by
Ken.
v4: Use CLAMP instead of MIN2(MAX2()). Suggested by Ken.

This prevents other code from seeing a swizzle of the 16th component
of a vector, for example.
NOTE: This is a candidate for the 7.11 branch.
