WidenVSELECTAndMask can fold (and it folds in this case) so we get a BUILD_VECTOR of constants as mask. convertMask() seems to work fine when the input is a vector of constants, and we still need to call it to extend/add elements at the end. but the current code just asserts on anything but a SETCC or AND/OR/XOR of 2xSETCC. This change was discussed briefly with Simon Pilgrim, who also suggests we might consider dropping this assertion in the future. Fixes PR33715. llvm-svn: 307508
