A comment in ieee754dp_mul indicates that the code is about to perform a 32b x 32b multiplication & keep the high 32b of the result. It appears this was copied from the single-precision multiplication code, since the code actually goes on to perform a 64b x 64b multiplication & keep the high 64b of the result. Fix the comment to indicate 64b. It appears also that this comment was copied verbatim along with the rest of the multiplication code into ieee754dp_maddf, which has since been renamed _dp_maddf. Fix the same issue there.
