    gccrs: Add regression tests for exclusive range pattern
    
    Add a few test to check the exclusive range pattern feature. This feature
    is experimental and shall not be enabled in stable rust.
    
    gcc/testsuite/ChangeLog:
    
            * rust/compile/exclusive_range_pattern.rs: New test.
            * rust/compile/exclusive_range_pattern_feature_gate.rs: New test.
