Florian Hahn 8240cf337a [VPlan] Always set flags for overflowing ops etc via VPIRFlags. (#179138) ...

Enforce that all VPInstructions set the correct OpType of the VPIRFlags.
Flag mis-matches (e.g. VPInstruction Add without `OverflowingBinOp`
being set) can cause crashes (e.g. in CSE) or potentially mis-compiles.

Add a few helpers in VPBuilder to create common instructions with
correct flags.
