Ken-Patrick Lehrmann 5a3789a23f 9769: Improve value flow for ternary operator
In some cases, the condition of the ternary operator is assigned a known
value after the two possible results, and in such cases, we would not
take the opportunity to assign a value to the ternary operator (and to
the other parents in the ast).
This patch adds this capability.

This fixes false positive nullPointerRedundantCheck with the following
code:
```
void throwexception(int * buf)

    if (!buf)
        boost::throw_exception(std::bad_alloc());

9768: Fix ast with throw in the middle of return (#2678)
* 9768: Fix ast with throw in the middle of return

```
int f(bool x)
{
    return x ? 0 : throw 0;
}
```

The `throw` part was not included in the ast, leading to an invalid
ternary operator.

* 8526: Fix ast construction for ternary operator

This tries to decide a bit more properly when ':' can be part of a
ternary operator. More precisely, there are some times when we want to
delay the construction of the ast for ':', so that it is place
accordingly to the matching '?'.

Typically, this fixes an issue with
`return val < 0 ? throw 1 : val;`,
where the ast for ':' would be constructed during as part of the
`throw`, and the ast for `?` would be invalid.

This patch is a bit of a hardcode, stating that we don't expect ':'
inside a throw, unless there is a complete ternary operator in there
(there can't be a range based for loop, a case in a switch). When we
reach ':', we know we are and the end of the `throw`.

Fix some false positive in loop forward analysis (#2669)
* Fix some false positive in loop forward analysis

In cases like:
```
bool b();
void f()
{
    int val[50];
    int i, sum=0;
    for (i = 1; b() && i < 50; i++)
        sum += val[i];
    for (; i < 50; i++)
        sum -= val[i];
}
```
The forward analysis assumed the second loop was entered, and we ended
up with false positive in it:
 `Array 'val[50]' accessed at index 50, which is out of bounds`

PKEuS dc701276de Optimizations to ValueFlow and ForwardAnalyzer:
- Remove errorPath of a value on assignment (this fixes enormous memory consumption for code with many subsequent assignments)
- De-virtualized a simple get function that was virtual for no reason
- Cloned function isAliasOf() for single values to avoid instantiating unnecessary std::list objects (
- Replaced a couple of trivial Token::Match/simpleMatch expressions by direct comparison
- Treat enumerators as literal values
