  Changed paths:
    M llvm/lib/DebugInfo/DWARF/DWARFExpression.cpp
    M llvm/test/DebugInfo/X86/DW_OP_call_ref_unexpected.s
    M llvm/test/tools/llvm-dwarfdump/X86/verify_broken_exprloc.s

  Log Message:
  -----------
  [DebugInfo] Dump raw data in a case of decoding error of an expression.

It looks like that was an initial intention, but some code paths in
`DWARFExpression::Operation::extract()` did not initialize `EndOffset`
properly.
