Missing code generation for sum of integer matrices

[resting-dove]

Related issue https://github.com/daphne-eu/daphne/issues/662#issue-2154646268 Daphne supports code generation for the sum(A) operation of f64 valued matrices A. Code generation is not available for f32, si64, si32, ui64, ui32 value types.

Code to produce the issue:

N = 4;
A = as.matrix<f32>(fill(3.0, N, N));
print(sum(A));

Output:

error: failed to materialize conversion for result #0 of operation 'daphne.sumAll' that remained live after conversion
module {
  func.func @main() {
    %0 = "daphne.constant"() {value = 4 : index} : () -> index
    %1 = "daphne.constant"() {value = false} : () -> i1
    %2 = "daphne.constant"() {value = true} : () -> i1
    %3 = "daphne.constant"() {value = 3.000000e+00 : f64} : () -> f64
    %4 = "daphne.fill"(%3, %0, %0) : (f64, index, index) -> !daphne.Matrix<4x4xf64>
    %5 = "daphne.cast"(%4) : (!daphne.Matrix<4x4xf64>) -> !daphne.Matrix<4x4xf32>
    %6 = "daphne.sumAll"(%5) : (!daphne.Matrix<4x4xf32>) -> f32
    "daphne.print"(%6, %2, %1) : (f32, i1, i1) -> ()
    "daphne.return"() : () -> ()
  }
}

Code generation for f32, si64 and ui64 value types is added in #653.
