    gccrs: Rename label getter in ContinueExpr
    
    gcc/rust/ChangeLog:
    
            * ast/rust-ast-collector.cc (TokenCollector::visit):
            Call unchecked getter.
            * ast/rust-ast-visitor.cc (DefaultASTVisitor::visit):
            Likewise.
            * ast/rust-ast.cc (ContinueExpr::as_string): Likewise.
            * hir/rust-ast-lower-expr.cc (ASTLoweringExpr::visit): Likewise.
            * resolve/rust-ast-resolve-expr.cc (ResolveExpr::visit): Likewise.
            * resolve/rust-late-name-resolver-2.0.cc (Late::visit): Likewise.
            * ast/rust-expr.h: Add new getter for the optional and rename getter
            to get_label_unchecked.
