Joseph Myers 875cd54855 Use libm_alias_double for sparc. 
Continuing the preparation for additional _FloatN / _FloatNx function
aliases, this patch makes sparc libm function implementations use
libm_alias_double to define function aliases (with consequent
simplification where compat symbol handling is now done by those
macros rather than locally in architecture-specific code).

Tested with build-many-glibcs.py for all its sparc configurations that
installed stripped shared libraries are unchanged by the patch.

Adhemerval Zanella a55430cb0e sparc: Assume VIS3 support 
This patch assumes VIS3 support by binutils, which is supported since
version 2.22.  This leads to some code simplification, mostly on
multiarch build where there is only one variant instead of previously
two (whether binutils supports VIS3 instructions or not).

For multiarch files where HAVE_AS_VIS3_SUPPORT was checked and
the default implementation was built with a different name, a new
file with (implementation with -generic appended) is added.

Checked on sparc64-linux-gnu and sparcv9-linux-gnu.
