Log:
    compiler: better abstraction layer for diagnostics.
    
    Introduce an abstraction layer for reporting diagnostics, so as to avoid
    directly using the native GCC interfaces such as "error_at",
    "warning_at", "open_quote", "close_quote", etc.  The new interfaces have
    the same look and feel as the GCC equivalents, but make calls into
    back-end functions to allow the back end to select the proper final
    reporting routine.
