only be accessed with SImode loads. This works around a bug in the
combiner where a constant pool reference is temporarily converted
to an HImode load, which is then assumed to zero-extend based on
our definition of LOAD_EXTEND_OP. This is wrong because the high
bits of a 16-bit value in the constant pool are now sign-extended
