Add a check for duplicate if statements
...
This will warn for this:
```cpp
int f(int val)

int i = 0;
if( val & 0xff)
i = 1;
if( val & 0xff)
i = 1;
return i;
}

CheckStl: add missing error ID iterators2 ( #1576 )
...
due to equal arguments...
* iterators1 (`CheckStl::iteratorsError(const Token*, const std::string&, const std::string&)`) and
* iterators2 (`CheckStl::iteratorsError(const Token*, const Token*, const std::string&, const std::string&)`)
... produced equal messages. Equal messages were filtered-out `CppCheck::reportErr(const ErrorLogger::ErrorMessage&)`.
So the error iterators2 disapeared from the error list.

Valueflow: Fix right shift with more than 31 bits ( #1553 )
...
When comparing if the shift is large enough to make the result zero, use
an unsigned long long to make sure the result fits. Also, a check that
avoids setting the value if the shift is equal to or larger than the
number of bits in the operand (this is undefined behaviour). Finally,
add a check to make sure the calculated value is not too large to store.
Add test cases to cover this.
This was detected by an MSVC warning.

converted to 64 bits (was 64-bit shift intended?)
