llvm-mc: Symbols in a relocatable expression of the (a - b + cst) form are
...
allowed to be undefined when the expression is seen, we cannot enforce the
same-section requirement until the entire assembly file has been seen.

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.

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.
