[llvm-bcanalyzer] Fixed error 'Expected<T> must be checked before access or destruction'
After rL365286 I had failing test:
LLVM :: tools/gold/X86/v1.12/thinlto_emit_linked_objects.ll
It was failing with the output:
$ llvm-bcanalyzer --dump llvm/test/tools/gold/X86/v1.12/Output/thinlto_emit_linked_objects.ll.tmp3.o.thinlto.bc
Expected<T> must be checked before access or destruction.
Unchecked Expected<T> contained error:
