Jonas Paulsson 90d0031df7 [DAGTypeLegalizer] Handle ZERO_EXTEND of promoted type in WidenVecRes_Convert.
On SystemZ, a ZERO_EXTEND of an i1 vector handled by WidenVecRes_Convert()
always ended up being scalarized, because the type action of the input is
promotion which was previously an unhandled case in this method.

This fixes https://bugs.llvm.org/show_bug.cgi?id=47132.

Differential Revision: https://reviews.llvm.org/D86268

Patch by Eli Friedman.
