Fix the static initializer build with UBSan

The idea is borrowed from the upstream 56ac70e (trunk@212499).
Without the check initializer is not fold to constant and therefore structure
cannot be initialized.

* gcc/fold-const.c (tree_single_nonzero_warnv_p): Check if local object
is WEAK to remove then NULL check.
* gcc.dg/ubsan/static-init-null.c: New testcase.
