compiling without -mfmovd, movsf_ie isn't taken into account for
mode switching. We could check in machine_dependent_reorg for
cases where we know we are in single precision mode, but there is
interface to find that out during reload, so we must avoid
choosing an fldi alternative during reload and thus failing to
allocate a scratch register for the constant loading. */
