When converting dbg.declares, if the described value is a [s|z]ext, refer to the ext directly instead of referring to its operand. This fixes a narrowing bug (the debugger got the sign of a variable wrong, see llvm.org/PR35400). The main reason to refer to the ext's operand was that an optimization may remove the ext itself, leading to a dropped variable. Now that InstCombine has been taught to use replaceAllDbgUsesWith (r336451), this is less of a concern. Other passes can/should adopt this API as needed to fix dropped variable bugs.
