[PATCH] Allow % to work on vectors

[Andrew Pinski]

Hi,
  This patch allows for % (remainder) to work on integer vectors.
This does not add any patterns that optimize % to just division with a
subtraction of vector types though, that will be for a seperate patch.

OK? Bootstrapped and tested on i686-linux-gnu with no regressions.

Thanks,
Andrew Pinski

ChangeLog:
* c-typeck.c (build_binary_op): Allow % on integal vectors.
* doc/extend.texi (Vector Extension): Document that % is allowed too.
