[PATCH] D36781: [InstCombine] Make folding (X >s -1) ? C1 : C2 --> ((X >>s 31) & (C2 - C1)) + C1 support splat vectors

Added back the type checks and added an explicit truncate test. We don't want to look through a truncate here. Even if decomposeBitTestICmp starts looking through truncates, we need to prevent is for this usage.
