Joseph Myers 26007a2f68 Support _Float32 in libm_alias_float. ...

This patch makes the libm_alias_float macro support creating _Float32
aliases, in preparation for enabling glibc support for that type.

Tested for x86_64; also tested with build-many-glibcs.py in
conjunction with other _Float32 changes.

	* sysdeps/generic/libm-alias-float.h: Include <bits/floatn.h>.
	[__HAVE_FLOAT32 && !__HAVE_DISTINCT_FLOAT32]
	(libm_alias_float_other_r): Create f32 alias.
	(libm_alias_float_r): Use semicolon before call to
	libm_alias_float_other_r.
