Add check for unnecessary search before insertion
...
This will warn for cases where searching in an associative container happens before insertion, like this:
```cpp
void f1(std::set<unsigned>& s, unsigned x) {
if (s.find(x) == s.end()) {
s.insert(x);
}
}
void f2(std::map<unsigned, unsigned>& m, unsigned x) {
if (m.find(x) == m.end()) {
m.emplace(x, 1);
} else {
m[x] = 1;
}
}
```
In the case of the map it could be written as `m[x] = 1` as it will create the key if it doesnt exist, so the extra search is not necessary.
I have this marked as `performance` as it is mostly concerning performance, but there could be a copy-paste error possibly, although I dont think thats common.

* Add support for simple c++ 11 type ailases like: using INT = int;
Only types supported by ValueType are supported. Complex types like
function pointers are not supported. Template type aliases are not
supported.
* Fix crash when type in using type alias is simplified away.
This fixes a crash when size_t is replaced with unsigned long in: using
size_t = unsigned long; by the tokenizer.
This does not fix the problem where Tokenizer::simplifyPlatformTypes()
simplifies away size_t in other cases. This is only a problem when the
new type is different from the platform type.
