Fix handling of namespace scope with several bodystarts ( #3438 )
...
Follow up to 0093452bed
.
Give the proper end to getVariableList, since it might not be bodyEnd.
Before that, getVariableList would add the same variables in several
unrelated scopes, and all kind of false positive would follow.
For instance, with the case I added in the unit-tests, I had:
```
../code.cpp:15:18: warning: The struct 'is_A' defines member variable with name 'foo' also defined in its parent struct 'is_A_impl'. [duplInheritedMember]
static const int foo = 8;
^
../code.cpp:15:18: note: Parent variable 'is_A_impl::foo'
static const int foo = 8;
^
../code.cpp:15:18: note: Derived variable 'is_A::foo'
static const int foo = 8;
^
../code.cpp:15:18: style: struct member 'has_A::foo' is never used. [unusedStructMember]
static const int foo = 8;
^
../code.cpp:15:18: style: struct member 'is_A::foo' is never used. [unusedStructMember]

```

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.
