Use libm_alias_double for dbl-64 logb.
This patch makes dbl-64 logb use libm_alias_double. Both the dbl-64 and dbl-64/wordsize-64 versions are changed, and the ldbl-opt version is removed. Because of multiarch wrappers, the changed implementations are made not to define aliases at all if __logb 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 (except on alpha where changes from using the wordsize-64 version are expected). * sysdeps/ieee754/dbl-64/s_logb.c: Include <libm-alias-double.h>. (logb): Define using libm_alias_double, only if [!__logb]. * sysdeps/ieee754/dbl-64/wordsize-64/s_logb.c: Include <libm-alias-double.h>. (logb): Define using libm_alias_double, only if [!__logb]. * sysdeps/ieee754/ldbl-opt/s_logb.c: Remove file. * sysdeps/powerpc/powerpc32/power4/fpu/multiarch/s_logb-ppc32.c (weak_alias): Do not undefine and redefine. (strong_alias): Likewise. * sysdeps/powerpc/powerpc64/fpu/multiarch/s_logb-ppc64.c (weak_alias): Likewise. (strong_alias): Likewise.
