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.

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

Debug info should aim to be either accurate or absent.

Identify when a lexical scope is split in to multiple instruction ranges. Emit such ranges using DW_AT_ranges.
This patch fixes bug (PR6894) introduced by previous version of this patch.

x86_64-unknown-gnu-linux.
