Use libm_alias_double for some dbl-64 functions. Continuing the move of libm aliases to common macros that can create _FloatN / _FloatNx aliases in future, this patch converts some dbl-64 functions to using libm_alias_double, thereby eliminating the need for some ldbl-opt wrappers. This patch deliberately limits what functions are converted so that it can be verified by comparison of stipped binaries. Specifically, atan and tan are excluded because they first need converting to being weak aliases; fma is omitted as it has additional complications with versions in other directories (removing the ldbl-opt version can e.g. cause the ldbl-128 version to be used instead of dbl-64); and functions that have both dbl-64/wordsize-64 and ldbl-opt versions are excluded because ldbl-opt currently always wraps dbl-64 function versions, so changing those will result in platforms using both ldbl-opt and dbl-64/wordsize-64 (i.e. alpha) starting to use the dbl-64/wordsize-64 versions of those functions (which is good, as an optimization, but still best separated from the present patch to get better validation). Tested for x86_64, and tested with build-many-glibcs.py that installed stripped shared libraries are unchanged by the patch. * sysdeps/ieee754/dbl-64/s_asinh.c: Include <libm-alias-double.h>.

Use libm_alias_double for some dbl-64 functions. Continuing the move of libm aliases to common macros that can create _FloatN / _FloatNx aliases in future, this patch converts some dbl-64 functions to using libm_alias_double, thereby eliminating the need for some ldbl-opt wrappers. This patch deliberately limits what functions are converted so that it can be verified by comparison of stipped binaries. Specifically, atan and tan are excluded because they first need converting to being weak aliases; fma is omitted as it has additional complications with versions in other directories (removing the ldbl-opt version can e.g. cause the ldbl-128 version to be used instead of dbl-64); and functions that have both dbl-64/wordsize-64 and ldbl-opt versions are excluded because ldbl-opt currently always wraps dbl-64 function versions, so changing those will result in platforms using both ldbl-opt and dbl-64/wordsize-64 (i.e. alpha) starting to use the dbl-64/wordsize-64 versions of those functions (which is good, as an optimization, but still best separated from the present patch to get better validation). Tested for x86_64, and tested with build-many-glibcs.py that installed stripped shared libraries are unchanged by the patch. * sysdeps/ieee754/dbl-64/s_asinh.c: Include <libm-alias-double.h>.
