Assertion failure "Instruction does not dominate all uses!" when block captures variables of non-trivially destructible type used in static local initializer

Clang crashes with an LLVM IR verification error when a block literal captures variables of a type with a non-trivial destructor and is used to initialize a static const local variable.

$ cat test.cpp

```c++
struct S {
~S();
};

void test() {
S s1, s2;

static const int i = ^(void) {
(void)s1;
(void)s2;
return 0;
}();
}
```

$ clang++ -std=c++20 -fblocks test.cpp -c
```
Instruction does not dominate all uses!
