[PATCH] Fix PR 69282: ICE on 464.h264ref at -O3


Hi,
  The problem is that even though expand knows how to expand
VEC_COND<a, b, c> when there is no vcond_mask pattern,
expand_vec_cond_expr_p returns false.  So this patch allows
expand_vec_cond_expr_p to try the next part of the function if there
is no vcond_mask pattern.

OK? Bootstrapped and tested on aarch64-linux-gnu with no regressions.

Thanks,
Andrew Pinski

ChangeLog:
* optabs-tree.c (expand_vec_cond_expr_p): Don't early return if
get_vcond_mask_icode returns false.

Testsuite/ChangeLog:
* gcc.c-torture/compile/20160205-1.c: New testcase.
