tree-optimization/96978 - fix fallout of BB vectorization of live stmts
This avoids looking at STMT_VINFO_LIVE_P when vectorizing BBs.

PR tree-optimization/96978
* tree-vect-stmts.c (vectorizable_condition): Do not
look at STMT_VINFO_LIVE_P for BB vectorization.
(vectorizable_comparison): Likewise.
