`uint_bits_to_fit`: Inferred an any meta-type with traits

Code to reproduce

pipeline(N) recursive_fft<#uint N, #uint FloatWidth, #uint FloatFracBits>(
    clk: clock, 
    twiddle_port: Port<{uint_bits_to_fit(N)}, int<1>>
) {
    gen if N == 1 {

    } else {

    }
   // inst({N / 2}) 
   // inst({N / 2}) 
}
