Unable to search for numerical constants in the array

Array like `int[]` got initialized with
```
ldc.i4.s array_length
newarr T
dup
ldtoken field valuetype <PrivateImplementationDetails>::Field
call void System.Runtime.CompilerServices.RuntimeHelpers::InitializeArray(class System.Array, valuetype System.RuntimeFieldHandle)
```
