Removed the DumpSymbolsandMacros and LoadSymbolsandMacros MCStreamer API as

Browse Source 
the parsing of the .dump and .load should be done in the assembly parser and
not have any need for an MCStreamer API.  Changed the code for now so these
just produce an error saying these specific directives are not yet implemented
since they are likely no longer used and may never need to be implemented.
