[LLVM][AArch64] Fix invalid use of AArch64ISD::UZP2 in performConcatVectorsCombine. (#104774)
UZP2 requires both operands to match the result type but the combine tries to replace a truncate by passing the pre-truncated operands directly to an UZP2 with the truncated result type. This patch nop-casts the operands to keep the DAG consistent. There should be no changes to the generated code, which is fine as it.
This patch also enables more target specific getNode() validation for fixed length vector types.
