  Changed paths:
    M lld/ELF/SymbolTable.cpp
    M lld/test/ELF/wrap-dynamic-undef.s
    M lld/test/ELF/wrap-no-real.s
    A lld/test/ELF/wrap-shlib-undefined.s

  Log Message:
  -----------
  [ELF] --wrap: don't error `undefined reference to __real_foo` (--no-allow-shlib-undefined) if foo is a wrapped definition

This is a regression after D51283.

Also, export `foo` if `__real_foo` is referenced by a shared object.
