When generating a SUBREG from V16QI to V2HF, validate_subreg fails since
V2HF is a floating point vector and its size (4 bytes) is smaller than its
natural size (word size). Insert an extra move with a QI vector SUBREG of
the same size to avoid validate_subreg failure.

Handle 8/4/2 bytes.
(remove_redundant_vector_load): If the mode size is smaller than
its natural size, first insert an extra move with a QI vector
SUBREG of the same size to avoid validate_subreg failure.
