I've tested that one; no more ICE, and bit-identical code for all target
libraries, so I suppose this is good to commit (Andrew, Julian)? If approving
this patch, please respond with "Reviewed-by: NAME <EMAIL>" so that your effort
will be recorded in the commit log, see <https://gcc.gnu.org/wiki/Reviewed-by>.
