5da38aa11d Merge 'core: fix concat function wrong start_register' from Sonny 
## What does PR do?
- fix concat function wrong start_register

## Current behavior
- addr 4 `r[1]=func(r[1..])`
- `r[1]` is target register to store the result, should not be the start reg of the function arguments
- it should be `r[1]=func(r[2..])` where
  - `r[2]` is the start of arguments
  - `r[1]` is target register to store the result

```
