remainder, remainderf, remainderl: Fix computation for large quotients.
* lib/remainder.c: Completely rewritten.
* lib/remainderf.c (remainderf): Use implementation of remainder.c with
USE_FLOAT.
* lib/remainderl.c (remainderl): Use implementation of remainder.c with
USE_LONG_DOUBLE.
* modules/remainder (Depends-on): Add isfinite, signbit, fabs, fmod,
isnand, isinf. Remove round, fma.
* modules/remainderf (Files): Add lib/remainder.c.
(Depends-on): Add isfinite, signbit, fabsf, fmodf, isnanf, isinf.
Remove roundf, fmaf.
* modules/remainderl (Files): Add lib/remainder.c.
(Depends-on): Add float, isfinite, signbit, fabsl, fmodl, isnanl,
isinf. Remove roundl, fmal.
* m4/remainder.m4 (gl_FUNC_REMAINDER): Update computation of
REMAINDER_LIBM.
* m4/remainderf.m4 (gl_FUNC_REMAINDERF): Update computation of
REMAINDERF_LIBM.
* m4/remainderl.m4 (gl_FUNC_REMAINDERL): Update computation of
REMAINDERL_LIBM.
