Use libm_alias_double for dbl-64 atan, tan [committed]

- Subject: Use libm_alias_double for dbl-64 atan, tan [committed]
- Authentication-results: sourceware.org; auth=none
This patch makes the dbl-64 atan and tan implementations use
libm_alias_double, removing the corresponding ldbl-opt wrappers.
Tested for x86_64, and with build-many-glibcs.py. Installed stripped
shared libraries are unchanged on non-ldbl-opt platforms. For
ldbl-opt configurations, the patch has the effect of causing
compat_symbol to define atanl and tanl in terms of __atan and __tan
instead of in terms of atan and tan, which is enough to change the
installed stripped libm.so. Committed.
