ldexpl: Simplify for platforms where 'long double' == 'double'.
* lib/ldexpl.c (ldexpl) [HAVE_SAME_LONG_DOUBLE_AS_DOUBLE]: New
alternative implementation.
* m4/ldexpl.m4 (gl_FUNC_LDEXPL): Require gl_LONG_DOUBLE_VS_DOUBLE.
Determine LDEXPL_LIBM according to HAVE_SAME_LONG_DOUBLE_AS_DOUBLE.
* modules/ldexpl (Depends-on): Add ldexp. Update conditions.
