Change some methods in MCDwarf.cpp to be able to handle an arbitrary
...
MCStreamer instead of just MCObjectStreamer. Address changes cannot
be as efficient as we have to use DW_LNE_set_addres, but at least
most of the logic is shared.
This will be used so that, with CodeGen still using EmitDwarfLocDirective,
llvm-gcc is able to produce debug_line sections without needing an
assembler that supports .loc.

Change CodeGen to use .loc directives. This produces a lot more readable output

every address change anymore.

Update MCAssembler::EvaluateFixup to match the change in

Remove the WeakRefExpr hack, as the object writer now sees the weakref with
no extra effort needed.
Nothing else is using MCTargetExpr, but keep it for now.
Now that the ELF writer sees relocations with aliases, handle
.weak foo2
foo2:
.weak bar2
.set bar2,foo2
.quad bar2
the same way gas does and produce a relocation with bar2.

This moves most of the isUsed logic to the MCSymbol itself. With this we

ddunbar, this was the smallest compromise I could think of that lets us
accept gcc (and clang!) assembly.
