Do not emit stop point for CXXDefaultArgExpr. It results in suboptimial user experience.

21 int main() {
22  A a;

For example, here user would expect to stop at line 22, even if A's constructor leads to a call through CXXDefaultArgExpr.

This fixes ostream-defined.exp regression from gdb testsuite.
