[VPlan] Simplify 'or x, true' -> true.
Add additional OR simplification to fix a divergence between legacy and
VPlan-based cost model.
This adds a new m_AllOnes matcher by generalizing specific_intval to
int_pred_ty, which takes a predicate to check to support matching both
specific APInts and other APInt predices, like isAllOnes.
Fixes https://github.com/llvm/llvm-project/issues/131359.
