gcc: remove atan from edom_only_function
According to the man page, atan does not produce an error. According to the
C23
standard draft (N3088), a range error occurs for atan if a nonzero x is too
close to zero. Neither of them mentions that atan will result in a domain
error.
gcc/ChangeLog:
* tree-call-cdce.cc (edom_only_function): Remove atan.
