glsl: Add lowering pass for ir_triop_vector_insert
This will eventually replace do_vec_index_to_cond_assign. This lowering pass is called in all the places where do_vec_index_to_cond_assign or do_vec_index_to_swizzle is called. v2: Use WRITEMASK_* instead of integer literals. Use a more concise method of generating broadcast_index. Both suggested by Eric. v3: Use a series of scalar compares instead of a single vector compare. Suggested by Eric and Ken. It still uses 'if (cond) v.x = y;' instead of conditional assignments because ir_builder doesn't do conditional assignments, and I'd rather keep the code simple.
