  4. [COFF] Fix /export:foo=bar when bar is a weak alias

    When handling exports from the command line or from .def files, the
    linker does a "fuzzy" string lookup to allow finding mangled symbols.
    However, when the symbol is re-exported under a new name, the linker has
    to transfer the decorations from the exported symbol over to the new
    name. This is implemented by taking the mangled symbol that was found in
    the object and replacing the original symbol name with the export name.

    Before this patch, LLD implemented the fuzzy search by adding an
    undefined symbol with the unmangled name, and then during symbol
    resolution, checking if similar mangled symbols had been added after the
    last round of symbol resolution. If so, LLD makes the original symbol a
    weak alias of the mangled symbol. Later, to get the original symbol
    name, LLD would look through the weak alias and forward it on to the
    import library writer, which copies the symbol decorations. This
    approach doesn't work when bar is itself a weak alias, as is the case in
    asan. It's especially bad when the aliasee of bar contains the string
    "bar", consider "bar_default". In this case, we would end up exporting
    the symbol "foo_default" when we should've exported just "foo".

    To fix this, don't look through weak aliases to find the mangled name.
    Save the mangled name earlier during fuzzy symbol lookup.
