Zoltan Somogyi a30c7c32b6 Revise the code printing progress messages.
compiler/passes_aux.m:
    To get the compiler's help in locating all the call sites
    to write_{pred,proc}_progress_message, change the argument order,
    to one that is better anyway.

    Print both the initial "% " at the start of the message, and the space
    between the message and the id of the predicate or procedure, so that
    callers don't have to. The fact that one caller was missing the "% "
    was the motive for this diff.

    After each message, flush the output. This is required in some use cases.
    Some call sites had a call to io.flush_output, but they could easily flush
    the wrong output stream.

    Conform to the changes above. Delete messages that should never have
    been there, such as those that would print "done" followed by the
    predicate/procedure id.

    In some places improve predicate names and/or comments.
