Reid Kleckner 3a66c1cb58 [DebugInfo] Insert DW_OP_deref when spilling indirect DBG_VALUEs ... Summary: This comes up in optimized debug info for C++ programs that pass and return objects indirectly by address. In these programs, llvm.dbg.declare survives optimization, which causes us to emit indirect DBG_VALUE instructions. The fast register allocator knows to insert DW_OP_deref when spilling indirect DBG_VALUE instructions, but the LiveDebugVariables did not until this change. This fixes part of PR34513. I need to look into why this doesn't work at -O0 and I'll send follow up patches to handle that.
