inlined function's arguments need a label to mark the start point because they are not directly attached to current function.

There is no need to force an line number entry (using previous location) for a temp label at unknown location.

Identify instructions, that needs a label to mark debug info entity, in advance. This simplifies beginScope().

This is used to track variable information.

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.

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.
