LOOKUP_ONLYCONVERTING means that non-conversion constructors are not tried.
DIRECT_BIND means that if a temporary is created, it should be created so
that it lives as long as the current variable bindings; otherwise it
- only lives until the end of the complete-expression.
+ only lives until the end of the complete-expression. It also forces

LOOKUP_SPECULATIVELY means return NULL_TREE if we cannot find what we are
after. Note, LOOKUP_COMPLAIN is checked and error messages printed
before LOOKUP_SPECULATIVELY is checked.
