Subject: Use libm_alias_double for alpha.

Continuing the preparation for additional _FloatN / _FloatNx function
aliases, this patch makes alpha libm function implementations use
libm_alias_double to define function aliases.  This also simplifies
the code because the compatibility for long double = double is handled
by libm_alias_double instead of locally in each source file.

Tested with build-many-glibcs.py for alpha-linux-gnu that installed
stripped shared libraries are unchanged by the patch.
