[StateHandling] Loop unrolling failed for `qvector` allocated from state

[1tnguyen]

Steps to reproduce:

#include <cudaq.h>

struct kernel {
  void operator()() __qpu__ {
    const std::vector<cudaq::complex> stateVector{1.0, 0.0, 0.0, 0.0};
    cudaq::qvector v(stateVector);
    h(v);
    mz(v);
  }
};

Command:

cudaq-quake <file name> | cudaq-opt --pass-pipeline='builtin.module(canonicalize,unrolling-pipeline,canonicalize)'

Error:

error: 'cc.loop' op not a constant upper bound loop
