Hans Wennborg fd12818ab8 Revert r313400 "[DebugInfo] Insert DW_OP_deref when spilling indirect DBG_VALUEs" ...

This caused asserts in Chromium. See http://crbug.com/766261

> 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.
