[google gcc-4_8] LIPO: insert static vars to varpool

[Rong Xu]

Hi,

For google gcc-4_8 branch only.

This is fixes the NULL pointer dereference in copy_tree_r due to empty
varpool_node returned.

Passed the ICE compilation. Other tests are ongoing.

Thanks,

        * cp/semantics.c (finish_compound_literal): Put static var to
        varpool. This is for LIPO only.
        * cp/call.c (make_temporary_var_for_ref_to_temp): Ditto.
