Florian Hahn aa24029319 [VPlan] Unroll VPReplicateRecipe by VF. (#142433) 
Explicitly unroll VPReplicateRecipes outside replicate regions by VF,
replacing them by VF single-scalar recipes. Extracts for operands are
added as needed and the scalar results are combined to a vector using a
new BuildVector VPInstruction.

It also adds a few folds to simplify unnecessary extracts/BuildVectors.

It also adds a BuildStructVector opcode for handling of calls that have
struct return types.

VPReplicateRecipe in replicate regions can will be unrolled as follow
up, turing non-single-scalar VPReplicateRecipes into 'abstract', i.e.
not executable.
