Describe remainder as primary and drem as alternative in the manual
In preparation for the documentation of _FloatN and _FloatNx variants of the remainder function, this patch changes the descriptions of remainder and drem, so that remainder is described as primary and drem as an alternative name for the same functionality. * manual/arith.texi (Remainder Functions): Describe remainder as primary and drem as an alternative name. Change the comment on remainder to ISO, since it is defined in ISO C99.
