    tree-vect-stmts.cc: Remove an unused shadowed variable
    
    When compiling tree-vect-stmts.cc with clang, it emits a warning:
    
      gcc/tree-vect-stmts.cc:14930:19: warning: unused variable 'mode_iter' [-Wunused-variable]
    
    And indeed, there are two mode_iter local variables in function
    supportable_indirect_convert_operation and the first one is not used
    at all.  This patch removes it.

            * tree-vect-stmts.cc (supportable_indirect_convert_operation):
            Remove an unused shadowed variable.
