Support _Float64, _Float32x in libm_alias_double.
This patch makes the libm_alias_double macros support creating _Float64 and _Float32x aliases, in preparation for enabling glibc support for those types. Tested for x86_64; also tested with build-many-glibcs.py in conjunction with other _Float64 / _Float32x changes. * sysdeps/generic/libm-alias-double.h: Include <bits/floatn.h>. (libm_alias_double_other_r_f64): New macro. (libm_alias_double_other_r_f32x): Likewise. (libm_alias_double_other_r): Use libm_alias_double_other_r_f64 and libm_alias_double_other_r_f32x. (libm_alias_double_r): Use semicolon before call to libm_alias_double_other_r. * sysdeps/ieee754/ldbl-opt/libm-alias-double.h: Include <bits/floatn.h>. (libm_alias_double_other_r_f64): New macro. (libm_alias_double_other_r_f32x): Likewise. (libm_alias_double_other_r): Use libm_alias_double_other_r_f64 and libm_alias_double_other_r_f32x.
