tree-optimization/120211 - constrain LOOP_VINFO_EARLY_BREAKS_LIVE_IVS more

The PR120089 fix added more PHIs to LOOP_VINFO_EARLY_BREAKS_LIVE_IVS
but not checking that we only add PHIs with a latch argument.  The
following adds this missing check.

PR tree-optimization/120211
* tree-vect-stmts.cc (vect_stmt_relevant_p): Only add PHIs
from the loop header to LOOP_VINFO_EARLY_BREAKS_LIVE_IVS.

* gcc.dg/vect/vect-early-break_135-pr120211.c: New testcase.
* gcc.dg/torture/pr120211-1.c: Likewise.
