f1c0daa6a7 Removed the DumpSymbolsandMacros and LoadSymbolsandMacros MCStreamer API as
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.

37b8fe7db3 llvm-mc: Diagnose misuse (mix) of defined symbols and labels.
- For example, we diagnose errors on:
--
a:
a = 10
--

 - For now we reject code like:
--
.long a
a = 10
--
   which "as" accepts (on Darwin).

reintroduce them later.

Also, don't require MCSection* when creating a symbol.

3624754e23 Add some scaffolding for a new experimental asmprinter
implementation.  The idea is that we want asmprinting to
work by converting MachineInstrs into a new MCInst class,
then the per-instruction asmprinter works on MCInst.  MCInst
and the new asmprinters will not depend on most of the 
llvm code generators.  This allows building diassemblers
that don't link in the whole llvm code generator.  This is
step #1 of many.
