Use libm_alias_double for dbl-64 modf.
This patch makes dbl-64 modf use libm_alias_double. Both the dbl-64 and dbl-64/wordsize-64 versions are changed, and the ldbl-opt version is changed to define the libc compat symbol only. Because of multiarch wrappers, the changed implementations are made not to define aliases at all if __modf is defined as a macro, as with other functions, so avoiding duplicate compat symbols while allowing those wrappers to be simplified. Tested for x86_64, and verified with build-many-glibcs.py that installed stripped shared libraries are unchanged by the patch. * sysdeps/ieee754/dbl-64/s_modf.c: Include <libm-alias-double.h>. (modf): Define using libm_alias_double, only if [!__modf]. * sysdeps/ieee754/dbl-64/wordsize-64/s_modf.c: Include <libm-alias-double.h>. (modf): Define using libm_alias_double, only if [!__modf]. * sysdeps/ieee754/ldbl-opt/s_modf.c (modfl): Only define libc compat symbol here. * sysdeps/powerpc/powerpc32/power4/fpu/multiarch/s_modf-ppc32.c (weak_alias): Do not undefine and redefine. (strong_alias): Likewise. * sysdeps/powerpc/powerpc64/fpu/multiarch/s_modf-ppc64.c (weak_alias): Likewise. (strong_alias): Likewise.
