  [DebugInfo][LoopVectorizer] Avoid dropping !dbg in optimizeForVFAndUF (#114243)

Prior to this patch, optimizeForVFAndUF may optimize the conditional
branch for a VPBasicblock to have a constant condition, but
unnecessarily drops the DILocation attachment when it does so; this
patch changes it to preserve the DILocation.
