Add missing operators <<= and >>=
...
This fixes issues (at least false positives) in code using them.
For instance:
```
unsigned compute(unsigned long long a) {
unsigned num = 0;
while (a > 0xFFFFFFFF) {
a >>= 32;
num += 32;
}
if (a > 0xFFFF) {
a >>= 16;
num += 16;
}
if (a > 0xFF) {
num += 8;
}
return num;
}
```
would give false positive:
```
cppcheck --enable=style sl3.cpp
Checking sl3.cpp ...
sl3.cpp:11:11: style: Condition 'a>0xFF' is always false [knownConditionTrueFalse]
if (a > 0xFF) {
^
sl3.cpp:3:14: note: Assuming that condition 'a>0xFFFFFFFF' is not redundant
while (a > 0xFFFFFFFF) {
^
sl3.cpp:11:11: note: Condition 'a>0xFF' is always false
if (a > 0xFF) {
^
```

The loop only checks astoperand1 and astoperand2. Simplify the condition
to loop over these instead of using a stack. Also, add a testcase for
when astoperand2 is negative.
