Need a checker to ensure that `inline if` is not propagated to low level

Branch: glob_array3_slh

We allow #inline annotation for if inside a for loop for SCT checking. We need a checker which will ensure that these inline if's are resolved and removed before generating assembly code.

inline fn __keccak_rho_offsets(inline int i, #msf reg u64 ms) -> inline int, #msf reg u64
{
  inline int r x y z t;

  r = 0;
  x = 1;
  y = 0;

  for t = 0 to 24 {
    #inline if (i == x + 5 * y) {        // this inline if should not be present in late stages of compilation
      r = ((t + 1) * (t + 2) / 2) % 64;
    }
    z = (2 * x + 3 * y) % 5;
    x = y;
    y = z;
  }

  return r, ms;
}
