// This file provides the interface to the LiveDebugVariables analysis.
//
// The analysis removes DBG_VALUE instructions for virtual registers and tracks
// live user variables in a data structure that can be updated during register
// allocation.
//
// After register allocation new DBG_VALUE instructions are emitted to reflect
// the new locations of user variables.
