pyos e96a5e8344 Implement JIT compilation, without a loop for now. 
It actually seems to work, so long as you only have one row that is. E.g.

    > select something(cast(number + 6 as Float64), cast(number + 2 as Float64)) from system.numbers limit 1';
    8

with this IR:

    define void @"something(CAST(plus(number, 6), 'Float64'), CAST(plus(number, 2), 'Float64'))"(void**, i8*, double*) {
    entry:
      %3 = load void*, void** %0
      %4 = bitcast void* %3 to double*
      %5 = load double, double* %4
      %6 = getelementptr void*, void** %0, i32 1
      %7 = load void*, void** %6
      %8 = bitcast void* %7 to double*
      %9 = load double, double* %8
      %10 = fadd double %5, %9
      store double %10, double* %2
      ret void
    }
