  [IR] Specify alloca with poison element count (#183072)

An alloca with a poison element count is undefined behavior.

This matches existing behavior of optimizations. This also matches the
behavior of llubui for `poison`, but llubi currently does not report
immediate UB for `undef` element counts. A future patch will fix that.
