  Log Message:
  -----------
  [DebugInfo] Use DW_OP_deref_size for DW_OP_LLVM_extract_bits (#97609)

Using DW_OP_deref can result in the debugger reading past the end of an
object into inaccessible memory, causing an error. Instead use
DW_OP_deref_size to make sure we don't read any bytes beyond what we
need to.
