commit f2d64d621e620b3b11fc4ed55f3e753ed6dc31e7

    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.
