Florian Hahn 6a9e8fc50c [VPlan] Introduce VPInstructionWithType, use instead of VPScalarCast(NFC) (#129706) ...

There are some opcodes that currently require specialized recipes, due
to their result type not being implied by their operands, including
casts.

This leads to duplication from defining multiple full recipes.

This patch introduces a new VPInstructionWithType subclass that also
stores the result type. The general idea is to have opcodes needing to
specify a result type to use this general recipe. The current patch
replaces VPScalarCastRecipe with VInstructionWithType, a similar patch
for VPWidenCastRecipe will follow soon.

There are a few proposed opcodes that should also benefit, without the
need of workarounds:
