Fixed a bug in expansion of array notations in if-statement conditions.
2013-06-03  Balaji V. Iyer  <balaji.v.iyer@intel.com>

       * c-typeck.c (c_finish_if_stmt): Added a check to see if the rank of the
       condition of the if-statement matches the rank of else-block and then-
       block when array notations are used.
       * c-parser.c (c_parser_declaration_or_fndef): Expanded array notation
       expression after the entire function body is parsed.
       (c_parser_expr_no_commas): Delayed creating array notation expressions
       to the end of function parsing.
       * c-array-notation.c (fix_conditional_array_notations_1): Expanded the
       whole if-statement instead of just the condition.
       (expand_array_notation_exprs): Added MODIFY_EXPR case.

       dg-option and an header comment.
