    Extract hardcoded error strings into a single place and replace them with enum. · d2c443b7

    I'd like to propagate bailout reason to cpu profiler.
    So I need to save it into heap object SharedFunctionInfo.
    But:
    1) all bailout reason strings spread across all the sources.
    2) they are native strings and if I convert them into String then I may have a performance issue.
    3) one byte is enough for 184 bailout reasons. Otherwise we need 8 bytes for the pointer.
    
    Also I think it would be nice to have error strings collected in one place.
    In that case we will get additional benefits:
    
    It allows us to keep this set of messages under control.
    It gives us a chance to internationalize them.
    It slightly reduces the binary footprint.
    
    From the other hand the developers have to add new strings into that enum.
