Split DbgVariable. Eventually, variable info will be communicated through frame index, or DBG_VALUE instruction, or collection of DBG_VALUE instructions. Plus each DbgVariable may not need a label.

the variable actually tracks.

N.B., several back-ends are using "HasCalls" as being synonymous for something
that adjusts the stack. This isn't 100% correct and should be looked into.

 - This is a hack, but I can't decide the best place to handle this. Chris?

Now, the .linkonce directive is emitted as part of MCSectionCOFF::PrintSwitchToSection instead of AsmPrinter::EmitLinkage since it is an attribute of the section the symbol was placed into not the symbol itself.

This means now 'llvm-ld a.bc b.bc' will preserve debug info appropriately.

Users can write broken code that emits the same label twice with asm renaming,
detect this and emit a fatal backend error instead of aborting.

Debug info should aim to be either accurate or absent.
