Use libm_alias_float for alpha.

Browse Source 
Continuing the preparation for additional _FloatN / _FloatNx function
aliases, this patch makes alpha libm function implementations use
libm_alias_float macros to define function aliases.  In the case of
the ABI compatibility for complex functions, libm_alias_float_other is
used, with the cfloat_versions macro adjusted to take a function name
argument without the trailing 'f' to facilitate this, and
cfloat_versions dealing with calling libm_alias_float_other (except
for clog10f, which doesn't use that macro because of the complexity
associated with __clog10f also being exported).

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

	* sysdeps/alpha/fpu/cfloat-compat.h: Include <libm-alias-float.h>.
	(cfloat_versions): Take function argument without trailing 'f'.
