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.
