* tree.h (constant_boolean_node): Adjust prototype.
* fold-const.c (fold_convert_loc): Move aggregate conversion
leeway down.
(constant_boolean_node): Make value parameter boolean, add
vector type handling.
(fold_unary_loc): Use constant_boolean_node.
(fold_binary_loc): Preserve types properly when folding
COMPLEX_EXPR <__real x, __imag x>.
* gimplify.c (gimplify_expr): Handle vector comparison.
* tree.def (EQ_EXPR, ...): Document behavior on vector typed
comparison.
* tree-cfg.c (verify_gimple_comparison): Verify vector typed
comparisons.
