[Test] Add for MOAC reinit miscompile.

On recent main, this test case fails verification with

```
SIL memory lifetime failure in @$s4main4doityyF: memory is not initialized, but should be
memory location:   %21 = struct_element_addr %20 : $*M4, #M4.s2    // user: %23
at instruction:   %23 = apply %22(%19, %21) : $@convention(thin) (@inout S, @inout S) -> ()

[...]

4.      While running pass swiftlang#173 SILFunctionTransform "MoveOnlyChecker" on SILFunction "@$s4main4doityyF".
