tree-optimization/110436 - bogus live/relevant for unused pattern
When we compute liveness and relevantness we have to make sure to
handle live but not relevant stmts in a way we can later vectorize
them. When the stmt uses only operands that do not need vectorization
we can just leave such stmts in place - but not in the case they
are recognized as patterns. Since we don't have a way to cancel
pattern recognition we have to force mark such stmts as relevant.
PR tree-optimization/110436
* tree-vect-stmts.cc (vect_mark_relevant): Expand dumping,
force live but not relevant pattern stmts relevant.
* gcc.dg/pr110436.c: New testcase.
