Report AND / OR expressions that do the same on left and right side

[RalfKoban]

We should report AND / OR conditions that do the same comparison on both sides (left and right).

Example for AND:

if (x == 42 && x == 42)

Example for OR:

if (x == 42 || x == 42)

Both should be fixed to:

if (x == 42)

Be also aware of unneeded parenthesis on one side:

if (x == 42 || (x == 42))
