re PR c++/82294 (Array of objects with constexpr constructors initialized from space-inefficient memory image)
PR c++/82294
PR c++/87436
* expr.h (categorize_ctor_elements): Add p_unique_nz_elts argument.
* expr.c (categorize_ctor_elements_1): Likewise. Compute it like
p_nz_elts, except don't multiply it by mult. Adjust recursive call.
Fix up COMPLEX_CST handling.
(categorize_ctor_elements): Add p_unique_nz_elts argument, initialize
it and pass it through to categorize_ctor_elements_1.
(mostly_zeros_p, all_zeros_p): Adjust categorize_ctor_elements callers.
* gimplify.c (gimplify_init_constructor): Likewise. Don't force
ctor into readonly data section if num_unique_nonzero_elements is
smaller or equal to 1/8 of num_nonzero_elements and size is >= 64
bytes.
* g++.dg/tree-ssa/pr82294.C: New test.
* g++.dg/tree-ssa/pr87436.C: New test.
