UseStatements::splitImportUseStatement(): fix PHPCS cross-version compatibility

For this class to be compatible with PHPCS 2.6.0 - `master`, two work-arounds need to be added:
1. Prior to PHPCS 3.4.1 `function`/`const` in `use function`/`use const` tokenized as T_FUNCTION/T_CONST instead of T_STRING when there is a comment between the keywords.
2. When a `function` or `const` would be used as the alias - which is in fact a parse error as both are reserved keywords -, the semi-colon/use group close curly is tokenized as T_STRING instead of as the appropriate token.
    With certain code patterns, this is currently still the case.

The second case should be considered a total edge case and no guarantee is given that this is 100% sorted now.
