    [inspector] Derive breakpoint hint based on resolved location. · ea3ee6da
    Benedikt Meurer authored
    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.
