Anton Yartsev 8a88b90817 [analyzer] Fix for PR23790 : constrain return value of strcmp() rather than returning a concrete value. ...

The function strcmp() can return any value, not just {-1,0,1} : "The strcmp(const char *s1, const char *s2) function returns an integer greater than, equal to, or less than zero, accordingly as the string pointed to by s1 is greater than, equal to, or less than the string pointed to by s2." [C11 7.24.4.2p3]
