546d750045 C#: Reintroduce getURL()
It turns out that we still need `getURL()` to account for cases where there is no
`getLocation()`. Not having `getURL()` for entities without a `getLocation()` results
in a `file://0:0:0:0` URL, which is not rendered in QL4E, unlike a `""` URL.

ada0115d6a C#: Remove getUrl() predicates
As described on https://lgtm.com/help/ql/locations#providing-location-information,
there is no need to provide a `getUrl()` predicate, when there is a `getLocation()`
predicate. Not only is it redundant, but it can also be slow because of string
construction.

c887dc89dc C#: Fix a bug in ThrowingCallable
A method such as

```
void M()
{
    throw new Exception();
}
```

was incorrectly not categorized as a `ThrowingCallable`, that is, a callable
that always throws an exception upon invocation.

3b0d1599ad C#: Teach guards library about unique assignments
For example, in

```
void M(object x)
{
    var y = x == null ? 1 : 2;
    if (y == 2)
        x.ToString();
}
```

the guard `y == 2` implies that the guard `x == null` must be false,
as the assignment of `2` to `y` is unique.

```
void M(object x)
{
    var y = x != null ? "" : null;
    if (y != null)
        x.ToString();
}
```

the guard `y != null` implies that the guard `x != null` must be true.

05b9519e9a C#: Handle multiple-field Boolean CFG splitting
The internal pre-SSA library was extended on 3e78c2671f
to include fields/properties that are local-scope-like. The CFG splitting logic
uses ranking of SSA definitions to define an (arbitrary) order of splits, but for
fields/properties the implicit entry definition all have the same line and column.
In effect, such SSA definitions incorrectly get the same rank. Adding the name
of the field/property to the lexicographic ordering resolves the issue.

ab7a094439 C#: Include CFG splits in Ssa::Definition::toString()
Just like syntax elements can be split in the control flow graph, so can SSA
definitions. To make this clear, and to make debugging easier, this commit
adds the splits as a prefix in the textual representation of SSA definitions.

3eb163f656 C#: Account for split SSA definitions in guards library
On 03e69e9945, I updated the guards library to account
for control flow graph splitting. However, the logic that relates SSA qualifiers for
the guard and the guarded expression was not updated accordingly.
