Git commit 7bbaa66b88b9c551d0b8f9835ebe5e253e351d5c by GitHub (on behalf of Florian Hahn) on 26/07/2026 at 18:07..
Reapply "[VPlan] Re-use VPSlotTracker when printing recipes for costs (NFC)." (#209003) (#211763)

This reverts commit 4c7948d06c93e8d233cd4733fd4107f3b68bc7bc. The commit
always constructs slot on first use, to fix compile-time regressions in
release builds.

Original message:
VPRecipeBase::dump() constructs a fresh VPSlotTracker instance on each
call. VPSlotTracker construction requires iterating over all recipes in
the plan, to number all VPValues.

To avoid doing lots of unnecessary work when printing VPlan costs,
construct a shared VPSlotTracker in VPCostContext, re-used by all
prints.

This can speed up debug output for large loops.
