Prefer the nonstatic member by converting unsigned to Register instead.

[DbgHistoryCalculator] Improve debug messages

I've found that a frequent source of debug information loss in optimized
code is due to DEBUG_VALUE intrinsics in a position of the instruction
stream that is outside the scope of the variable it describes.

Tracking these is pretty difficult with the existing debug messages of
the history calculator; this patch addresses the issue by making it
obvious when this event happens.

[DebugInfo] Fix: Variables that have no non-empty values being emitted when they have a DBG_VALUE_LIST

This patch fixes a simple bug where `DbgValueHistoryMap::hasNonEmptyLocation` was incorrectly handling DBG_VALUE_LIST instructions, treating empty values as non-empty, causing empty variables to be emitted into DWARF.
