Add _Float32 function aliases.

This patch concludes filling out TS 18661-3 support for different
types by adding *f32 function aliases of float functions to support
_Float32.  As with _Float64 and _Float32x, this is supported for all
glibc configurations.  As with the previous such patches there are
some x86 ulps updates because of inline functions present for float
but not for _Float32.  The patch also has the usual
bits/floatn-common.h update, symbol versions, ABI baselines updates,
test enablement and documentation.

Tested for x86_64 and x86, and with build-many-glibcs.py, with both
GCC 6 and GCC 7.
