`c2rust_run_static_initializers` fails with function-scoped statics

[brk]

Small reproducer:

struct foo { int* x; int nelts; };

#define ARR_SIZE(a) (sizeof(a)/sizeof(a[0]))

/* 
globals are supported
     const int global_arr[] = { 1, 2, 3 };
     const struct foo global_s[] = { global_arr, ARR_SIZE(global_arr) };
*/

int main() {
  static const int local_static_arr[] = { 1, 2, 3 };
  static const struct foo local_static_s[] = { local_static_arr, ARR_SIZE(local_static_arr) };
  return 0;
}

Relevant parts of translation:

static mut local_static_s: [foo; 1] = [foo { x: ::core::ptr::null_mut::<::core::ffi::c_int>(), nelts: 0, }; 1];

unsafe fn main_0() -> ::core::ffi::c_int {
    static mut local_static_arr: [::core::ffi::c_int; 3] = [ 1 as ::core::ffi::c_int, 2, 3 ];
    return 0 as ::core::ffi::c_int;
}

unsafe extern "C" fn c2rust_run_static_initializers() {
    local_static_s = [foo {
        x: &raw const local_static_arr as *const ::core::ffi::c_int as *mut ::core::ffi::c_int,
        nelts: ::core::mem::size_of::<[::core::ffi::c_int; 3]>()
            .wrapping_div(::core::mem::size_of::<::core::ffi::c_int>())
            as ::core::ffi::c_int,
    }];
}

which fails because local_static_arr is not in scope within fn c2rust_run_static_initializers().
