[AArch64][DebugInfo]Add Target hooks for InstrRef on AArch64 (#165953) 
This patch adds the target hooks required by Instruction Referencing for
the AArch64 target, as mentioned in
https://llvm.org/docs/InstrRefDebugInfo.html#target-hooks

Which allows the Instruction Referenced LiveDebugValues Pass to track
spills and restore instructions.

With this patch we can use the
`llvm/utils/llvm-locstats/llvm-locstats.py` to see the coverage
statistics on a clang.dSYM built with in RelWithDebInfo we can see:

coverage with dbg_value:

 I believe this should be a good indication that Instruction Referencing should be turned on for AArch64?
