Make ilogb wrappers type-generic.
This patch converts the ilogb wrappers (which set errno directly rather than doing anything with __kernel_standard) to use the type-generic template machinery. This is intended as preparation for adding llogb. Tested for x86_64 and x86, and tested compile for other architectures with build-many-glibcs.py. * math/w_ilogb_template.c: New file. Based on math/w_ilogb.c. * math/w_ilogb.c: Remove. * math/w_ilogbf.c: Likewise. * math/w_ilogbl.c: Likewise. * sysdeps/ieee754/ldbl-opt/w_ilogb.c: Likewise. * sysdeps/ieee754/ldbl-opt/w_ilogbl.c: Likewise. * math/Makefile (gen-libm-calls): Add w_ilogbF. (libm-calls): Remove w_ilogbF. * sysdeps/ieee754/ldbl-opt/math-type-macros-double.h (LDOUBLE_ilogbl_libm_version): New macro.
