Fix resolution streaming with incremental linking

[Jan Hubicka via Gcc-patches]

Hi,
this patch fixes streaming of resolution info when flag_incremental_link
== INCREMENTAL_LINK_NOLTO.  Here we want to stream the info from WPA to
ltrans as usual.

Bootstrapped/regtested x86_64-linux, tested with kernel LTO builds.
Plan to commit it later today.

        * gcc/lto-cgraph.cc (lto_output_node): Only drop resolution info when
        flag_incremental_link === INCREMENTAL_LINK_LTO.
