Refactor code to push DILocation prcessing into DwarfDebug.cpp from AsmPrinter.cpp.
...
This is same as r99772 (which was reverted) with just one meaningful difference where two source lines exchanged their positions.

Fix EmitSectionOffset incorrect argument. DwarfDebug is emitting debug info so isEH is always false. This was hiding until now from compilers because of default arguments. This was hiding from dwarf debug info users because for most of the platform isAbsoluteEHSectionOffsets() is same as isAbsoluteDebugSectionOffsets(). But Chris found it while updating dwarf printer to use MC*.
