The commit was reverted due to a regression in debug information of an optimized code test in lldb. This has since been addressed by: 1. rGf753e5be8239: [LiveDebugValues] Allow EntryValue with OP_deref expressions 2. rG055f2f04e658: [mem2reg][debuginfo] Handle op_deref when converting dbg.declare Differential Revision: https://reviews.llvm.org/D141381
