glsl: Add ir_triop_vector_insert
The new opcode is used to generate a new vector with a single field from
the source vector replaced. This will eventually replace
ir_dereference_array of vectors in the LHS of assignments.
v2: Convert tabs to spaces. Suggested by Eric.
v3: Add constant expression handling for ir_triop_vector_insert. This
prevents the constant matrix inversion tests from regressing. Duh.
