History
Joseph Myers 0d93b7fd7c Add _Float64, _Float32x function aliases. 
This patch continues filling out TS 18661-3 support by adding *f64 and
*f32x function aliases, supporting _Float64 and _Float32x, as aliases
for double functions.  These types are supported for all glibc
configurations.  The API corresponds exactly to that for _Float128 and
_Float64x.  _Float32 aliases to float functions remain to be added in
subsequent patches to complete this process (then there are a few
miscellaneous functions in TS 18661-3 to implement that aren't simply
versions of existing functions for new types).

The patch enables the feature in bits/floatn-common.h, adds symbol
versions and documentation with updates to ABI baselines, and arranges
for the libm functions for the new types to be tested.  As with the
_Float64x changes there are some x86 ulps updates because of header
inlines not used for the new types (and one other change to the
non-multiarch libm-test-ulps, which I suppose comes from using a
different compiler version / configuration from when it was last
regenerated).

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