Log:
PR c++/81888
* parser.c (cp_parser_decomposition_declaration): Reject just
BRACE_ENCLOSED_INITIALIZER_P initializers with nelts != 1 rather
than all such CONSTRUCTORs, and only if is_direct_init is true.

* g++.dg/cpp1z/decomp30.C: Add a test for structured binding with
= {} and = { a, a } initializers.
* g++.dg/cpp1z/decomp31.C: New test.
