Add new rules to detect the cases where sizeof is used in
function calls as a argument.
Also, for the patch mode third rule should behave same as
second rule with arguments reversed. So, change that as well.

Changes since v2:
- Add rules for function calls. This will behave as
more general rules and covers cases which were
covered by the rule in previous versions of the patch
- Change subject and commit log accordingly.
Changes since v1:
- Declare i as an expression instead of identifier to
cover more cases
