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.

* 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

Checkmemleakautovar: fix crash and FP ( #2196 )
...
This fixes crashes found by daca where valueType() is NULL. Also,
somewhat related, it removes warnings when casting to a type that is
unknown to cppcheck, for example, there is no longer a warning for the
following code:
void* f() {
void *x = malloc(1);
return (mytype)x;
}

as well as with other assignment checks in the code base.
