Reapply "[VPlan] Fold NOT into predicate of wide compares." (#130347)

2025-04-28T19:01:37+00:00

This reverts commit 8dd160f4767f971572eac065c8650d9202ff5bf9.

The recommit contains an adjustment to planContainsAdditionalSimplifications,
which considers changes to the original predicate for compares.

Original commit message:

Add simplification to fold negation into a compare, if the negation is
the only user of the compare. This removes a number of redundant
negations.

[VPlan] Also duplicated scalar-steps when it enables sinking scalars. (#136021)

2025-04-21T17:36:43+00:00

Extend sinking logic to duplicate scalar steps recipe if it enables
sinking, that is if all users in a destination block require all lanes.

This should be the last step before removing legacy sinkScalarOperands.

[VPlan] Set debug location for recipes in VPBB::executeRecipes.

2025-04-05T15:22:47+00:00

Set the debug location for each recipe before executing the recipe,
instead of ad-hoc setting the debug location during individual recipe
execution.

This simplifies the code and ensures that all recipe repsect the
recipe's debug location. There are some minor changes, where previously
we would re-use a previously set debug location.

[VPlan] Set and use debug location for VPScalarIVStepsRecipe.

This adds missing debug location for VPscalarIVStepsRecipe. The location
of the corresponding phi is used.

[VPlan] Remove no-op SCALAR-STEPS after unrolling. (#123655)

2025-03-25T12:57:24+00:00

After unrolling, there may be additional simplifications that can be
applied. One example is removing SCALAR-STEPS for the first part where
only the first lane is demanded.

This removes redundant adds of 0 from a large number of tests (~200),
many which I am still working on updating.
