    gccrs: resolve: Add ResolveExpr::funny_error
    
    ...and thread it through the constructors and the ResolveExpr::go ()
    method.
    
    This will be used for implementing the "break rust" Easter egg.
    
    gcc/rust/ChangeLog:
            * resolve/rust-ast-resolve-expr.h,
            resolve/rust-ast-resolve-expr.cc: Add ResolveExpr::funny_error
