Add DebugSSAUpdater class to track debug value liveness (#135349)
This patch adds a class that uses SSA construction, with debug values as
definitions, to determine whether and which debug values for a
particular variable are live at each point in an IR function. This will
be used by the IR reader of llvm-debuginfo-analyzer to compute variable
ranges and coverage, although it may be applicable to other debug info
IR analyses.
