[ScopInfo] Adapt indentation of instruction list printing.

Change the indention of the last brace to align with the opening line.

Before:

            Instructions {
                  %val = fadd double %arg, 2.100000e+01
                  store double %val, double* %A
                }

After:

            Instructions {
                  %val = fadd double %arg, 2.100000e+01
                  store double %val, double* %A
            }
