[DAGCombiner] Do not fold truncate(build_vector(..)) if it creates an illegal type
Summary:
It can be the case that a vector type is legal but the corresponding
scalar type is not legal for an architecture (i8 vs. v16i8 on AArch64).
Check if the scalar type created when folding
truncate(build_vector(x,y)) -> build_vector(truncate(x),truncate(y))
is legal if we are running after the type legalizer.
