CL 278914 introduced NameOffsetExpr to avoid copying ONAME nodes and hacking up their offsets, but evidently staticinit subtly depended on the prior behavior to allow dynamic initialization of blank variables. This CL refactors the code somewhat to avoid using NameOffsetExpr with blank variables, and to instead create dynamic assignments directly to the global blank node. It also adds a check to NewNameOffsetExpr to guard against misuse like this, since I suspect there could be other cases still lurking within staticinit. (This code is overdue for an makeover anyway.) Thanks to thanm@ for bisect and test case minimization. Fixes #43677.
