Rikard Falkeborn 4dbf006dc7 Fix severity of c++14 shifts with too many bits (#2213)
For c++14, shifting a variable with a value larger than or equal to the
number of bits in the variable is undefined. Left-shifting with a value
equal to the number of bits of the variable is implementation defined.

See also trac ticket #9306.

Rikard Falkeborn df800e35d4 Fix memleak FP with return with parenthesis (#2202)
* Fix memleak FP with return  with parenthesis

Fix FPs pointed out by daca@home on the following form:

    void* f(void) {
        void* x = malloc(1);
        return(x);
    }

Fix it by only skipping tokens if there is an actual match with a
variable. This allows to remove the special casing of "return;".

* Add testcase with cast
