When adjusting the existing tests, I aimed to avoid dealing with the special case in other tests if it's not necessary to do so (that is, avoid using `float` and `complex` as examples where we just need "some type"), and keep the tests for the special case mostly collected in the mdtest dedicated to that purpose.

Binary operations on booleans
Basic Arithmetic
We try to be precise and all operations except for division will result in Literal type.
a = True
b = False
reveal_type(a + a) # revealed: Literal[2]
reveal_type(a + b) # revealed: Literal[1]
reveal_type(b + a) # revealed: Literal[1]
reveal_type(b + b) # revealed: Literal[0]
reveal_type(a - a) # revealed: Literal[0]
reveal_type(a - b) # revealed: Literal[1]
reveal_type(b - a) # revealed: Literal[-1]
reveal_type(b - b) # revealed: Literal[0]
reveal_type(a * a) # revealed: Literal[1]
reveal_type(a * b) # revealed: Literal[0]
reveal_type(b * a) # revealed: Literal[0]
reveal_type(b * b) # revealed: Literal[0]
reveal_type(a % a) # revealed: Literal[0]
reveal_type(b % a) # revealed: Literal[0]
reveal_type(a // a) # revealed: Literal[1]

# Division
reveal_type(a / a) # revealed: float
reveal_type(b / a) # revealed: float
b / b # error: [division-by-zero] "Cannot divide object of type `Literal[False]` by zero"
a / b # error: [division-by-zero] "Cannot divide object of type `Literal[True]` by zero"
# bitwise OR
reveal_type(a | a) # revealed: Literal[True]
reveal_type(a | b) # revealed: Literal[True]
reveal_type(b | a) # revealed: Literal[True]
reveal_type(b | b) # revealed: Literal[False]
