[VPlan] Add initial loop-invariant code motion transform. (#107894) 
Add initial transform to move out loop-invariant recipes.

This also helps to fix a divergence between legacy and VPlan-based cost
model due to legacy using ScalarEvolution::isLoopInvariant in some
cases.

Fixes https://github.com/llvm/llvm-project/issues/107501.

[VPlan] Don't mark VPBlendRecipe as phi-like. 
VPBlendRecipes don't get lowered to phis and usually do not appear at
the beginning of blocks, due to their masks appearing before them.

This effectively relaxes an over-eager verifier message.
