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.

Fix issue 8910: Regression: ValueFlow: wrong conditional tokvalue

This fixes issue in:
```cpp
void f()
{
char stack[512];
RGNDATA *data;
if (data_size > sizeof (stack))
data = malloc (data_size);
else
data = (RGNDATA *)stack;
if ((char *)data != stack)
free (data); // <- data is not stack
}
```
It seems the `ProgramMemory` can't handle two known values(such as int and tok) together. So instead `ValueFlowAfterAssign` runs `ValueFlowForward` with tok values and then runs it with the other values.

Print test case name in assert
...
I sometimes find myself wondering which test cases I have broken when I fiddle with some check (since I then can try running these specific tests in the debugger, or make a small change and see if the tests pass). This PR adds the testclass and the test case names to the file and line number. I took special care to cover the case where an assert would be placed directly in the ```run()```-function, i.e., not inside a test case (from what I could see, no such case exists). If there is no need to handle this case, the code can be simplified (there wouldn't be need for the ```teardownTest()```-function for example).
The exact format for how to print the test name is very much up for discussion.
