Do not eagerly record known previous location. DBG_VALUE may not cause a new label due to one or other reason.

Debug info can now properly represent functions inside classes inside other functions.  Partial fix for Radar 7424645.

POD-like anyway, so we don't even care about calling their d'tors (DIEBlock
being the exception).

~6% less mallocs and ~1% compile time improvement on clang -O0 -g oggenc.c

they are faster than the old apis, particularly when
not going from an MDKindID like people should be
doing.

This is same as r99772 (which was reverted) with just one meaningful difference where two source lines exchanged their positions.

DW_AT_stmt_list attribute attached with a compile unit encodes offset of line number information for this compile unit in debug_line section. This offset is always zero when only one compile unit is emitted in a object file.

it allocates to DwarfDebug::DIEValues.

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*.
