Handle one- and multi-dimensional array return types correctly
Fixes https://github.com/eclipse/org.aspectj/issues/24, both the array return type matching as such as well as matching dimensionality patterns correctly. E.g., 'Foo*[]' is not the same as 'Foo*[][]'. This also works correctly in combination with asterisks, even for primitive types, i.e. 'in*[][]' correctly matches a 2-dimensional array of 'int'.
