Add DebugSSAUpdater class to track debug value livenessusers/SLTozer/debug-ssa-updater
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.
