This commit enhances the GIMPLE frontend by adding parsing support for __CLOBBER expressions. These expressions, previously uglified, are now parsed with a distinct identifier to avoid exposing internal implementation details. This change improves the fidelity of GIMPLE dumps for debugging and sets the stage for unifying dumping syntaxes in the future.
