Better handle noreturn or throwing functions in valueflow
...
Teaching cppcheck about `BOOST_THROW_EXCEPTION` and
`boost::throw_exception`, and using noreturn information from libraries
in value flow.
This fixes false positive nullPointerRedundantCheck with the following
code:
```
void throwexception(int * buf)
{
if (!buf)
boost::throw_exception(std::bad_alloc());
*buf = 0;
}

Improve isSameExpression for literals ( #2514 )
...
Improve isSameExpression() for literals with same value but different
representation, for example the following different ways of
representing 9 as double: 9.0, 0.9e1 and 0x1.2p3.
With this change, cppcheck can (for example) correctly detect that the
else if statements are always false in the following example:
void f(double x) {
if (x < 9.0) {}
else if (x < 0x1.2p3) {}
else if (x < 0.9e1) {}
}
