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`
* Fix style

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
