* typeck2.c (split_nonconstant_init_1): Pass the initializer directly,
rather than a pointer to it. Return true if the whole of the value
was initialized by the generated statements. Use
complete_ctor_at_level_p instead of count_type_elements.
gcc/

* tree.h (categorize_ctor_elements): Remove comment. Fix long line.
(count_type_elements): Delete.
(complete_ctor_at_level_p): Declare.
* expr.c (flexible_array_member_p): New function, split out from...
(count_type_elements): ...here. Make static. Replace allow_flexarr
parameter with for_ctor_p. When for_ctor_p is true, return the
number of elements that should appear in the top-level constructor,
otherwise return an estimate of the number of scalars.
(categorize_ctor_elements): Replace p_must_clear with p_complete.
(categorize_ctor_elements_1): Likewise. Use complete_ctor_at_level_p.
(complete_ctor_at_level_p): New function, borrowing union logic
from old categorize_ctor_elements_1.
(mostly_zeros_p): Return true if the constructor is not complete.
(all_zeros_p): Update call to categorize_ctor_elements.
* gimplify.c (gimplify_init_constructor): Update call to
categorize_ctor_elements. Don't call count_type_elements.
Unconditionally prevent clearing for variable-sized types,
otherwise rely on categorize_ctor_elements to detect
incomplete initializers.
