[LV] Add additional test coverage for cost modeling.

2024-06-26T09:18:01+00:00

Add missing tests uncovered by
https://github.com/llvm/llvm-project/pull/92555.

Includes test for https://github.com/llvm/llvm-project/issues/96294 and
https://github.com/llvm/llvm-project/issues/96328

Revert "Recommit "[VPlan] First step towards VPlan cost modeling. (#92555)""

2024-06-21T18:54:21+00:00

This reverts commit 242cc200ccb24e22eaf54aed7b0b0c84cfc54c0b and
eea150c84053035163f307b46549a2997a343ce9, as it is causing a build bot
failure and there have been a number of crashes reported at
https://github.com/llvm/llvm-project/pull/92555

[VPlan] Include IV phi and backedge cost in VPlan cost computation.

2024-06-20T19:44:17+00:00

In WebAssembly, costs != 0 are assigned to be backedge and induction
phis, so make sure we include those costs in the VPlan-based cost model.

This fixes a downstream crash with WebAssembly after 242cc200ccb
(https://github.com/llvm/llvm-project/pull/92555)
