  Log Message:
  -----------
  [llvm-profgen] CSProfileGenerator::generateLineNumBasedProfile - use cast<> instead of dyn_cast<> to avoid dereference of nullptr

The pointer is always dereferenced immediately below, so assert the cast is correct instead of returning nullptr

  Log Message:
  -----------
  [X86] combineConcatVectorOps - fold concat(movddup(x),movddup(y)) -> movddup(concat(x,y))

For AVX2+ targets this requires us to also recognise v4f64 concat(broadcast(x),broadcast(y)) -> movddup(concat(x,y))
