Hi,
This patch fixes https://gcc.gnu.org/bugzilla/show_bug.cgi?id=82235
For the following test case

struct Foo {
    Foo() {}
    explicit Foo(const Foo& aOther) {}
};
struct Bar {
    Foo m[1];
};
void test() {
    Bar a;
    Bar b = a;
}

the compiler issues an error when the compiler generated copy 
constructor of class Bar calls the explicit copy constructor of class 
Foo. The fix is to implement ISO C++/17 16.3.1.4 (over.match.copy) 
correctly.
I'm pinging this patch sent a while by Mukesh (I'm taking over from him 
about it). Any comments?
