81dca813cc Use copysign functions not __copysign functions in glibc libm.
Continuing the move to use, within libm, public names for libm
functions that can be inlined as built-in functions on many
architectures, this patch moves calls to __copysign functions to call
the corresponding copysign names instead, with asm redirection to
__copysign when the calls are not inlined (all cases are inlined
except for IBM long double for powerpc soft-float / e500v1).  This
eliminates the need for an inline function defining __copysign in
terms of __builtin_copysign.

Tested for x86_64, and with build-many-glibcs.py.

f433d0b3bb Use libm_alias_float for alpha.
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.
