Continuing the preparation for additional _FloatN / _FloatNx function aliases, this patch makes x86_64 libm function implementations use libm_alias_float to define function aliases, or libm_alias_float_other where the main name is defined with versioned_symbol. Tested with the glibc testsuite for x86_64, and tested with build-many-glibcs.py for all its x86_64 configurations that installed stripped shared libraries are unchanged by the patch. * sysdeps/x86_64/fpu/multiarch/e_exp2f.c: Include <libm-alias-float.h>. (exp2f): Define using libm_alias_float, or libm_alias_float_other if [SHARED]. * sysdeps/x86_64/fpu/multiarch/e_expf.c: Include <libm-alias-float.h>.
