comparesf2/comparedf2: use i32 instead of bool for return type. 

Note that this changes semantics:
    pub extern "C" fn __eqsf2(a: f32, b: f32) -> bool {
        cmp(a, b).to_le_abi() != 0
    }

is not the same as

    pub extern "C" fn __eqsf2(a: f32, b: f32) -> i32 {
        cmp(a, b).to_le_abi()
    }

However, compiler-rt does the latter, so this is actually
an improvement.
