Issue:
slither fails with no detectors results and sarif output
### Describe the issue:

Running for example

```
slither --exclude-informational tests/test_node_modules/node_modules/@openzeppelin/contracts/utils/math/Math.sol --sarif slither.sarif
```

Leads to a crash

[Bug]: Ill-typed IR for pop
### Describe the issue:

The IR for pop obtains a reference variable to the final array element and deletes it. The type of this reference variable is always uint256, but it should be equal to the type of the array's elements. 


### Code example to reproduce the issue:
```
contract Poptest {
    struct S {
        int x;
        int y;
    }
    S[] a;
    function poptest() internal {
        a.pop();
    }
}
```

### Relevant log output:

Issue:
Suggestion to make the recommendation in the `msgvalue-inside-a-loop` detector wiki clearer
### Describe the desired feature

Reference: https://github.com/crytic/slither/wiki/Detector-Documentation#msgvalue-inside-a-loop

This is the current recommendation for the `msgvalue-inside-a-loop` detector:

```solidity
Track msg.value through a local variable and decrease its amount on every iteration/usage.
```

This is a vague recommendation - it does not address the issue head-on, i.e., what mathematical technique the developer should use to remedy the bug.

My suggestions:

1. Recommend dividing by the number of `receivers`
2. Recommend providing an explicit array of amounts alongside the `receivers` array, and check that the sum of each element in that array matches `msg.value`


Discussion:
These are great suggestions and it's helpful to get feedback when these descriptions/ recommendations are not helpful. We definitely want to guide the developer to identify whether the issue affects them and, if so, how to fix it. If you'd like to work on this, the wiki can be updated here: https://github.com/crytic/slither/blob/ccad54263de5802c9893bd6eb151aa68d1a2cb95/slither/detectors/statements/msg_value_in_loop.py#L58-L83

Issue:
[Bug]: Type of tuple result of ABI-decode contains instances of Structure
### Describe the issue:

When the `abi.decode` function decodes a struct along with one or more other values, the type of the tuple on the left-hand side contains an instance of `Structure`, but I expect the tuple variables's `type` field to contain only instances of `Types`.

Instead of containing a `Structure` instance, the list should contain a `UserDefinedType` instance whose `type` field is a `Structure` instance.

### Code example to reproduce the issue:

```
pragma solidity =0.8.19;

contract StructTest {
    struct Detail {
        int x;
        int y;
    }

    function test(bytes calldata orderData) external {
        (int z, Detail memory testDetail) = abi.decode(orderData, (int, Detail));
        testDetail.x = 1;
    }

}

Probably related to this conversion https://github.com/crytic/slither/blob/0632751cc585d4c91f132d1597a4266d4db0ee3e/slither/slithir/convert.py#L1215-L1227
Yes, it looks like singletons are handled correctly and lists of types should be handled using the same logic.
