When setting a breakpoint on a line (in the DevTools front-end), the
front-end sends a columnNumber of 0 and the inspector automatically
resolves the actual location (in bytecode execution order). In order
to also support changing source code, the inspector memorizes a text
hint, and uses that to adjust the location upon reload. This hint was
however taken based on the original line and column numbers, rather than
the resolved location, which causes trouble when syntactic order doesn't
match execution order, as in case of `await o.m()`.
In order to address that we now remember the textual hint based on the
resolved location.
