[clang][bytecode] new interpreter fails with case ranges inside constexpr function

[k-arrows]

Reproducer:
https://godbolt.org/z/KorssdanW

constexpr int foo(int i) {
  switch (i) {
  case 11 ... 12:
    return 4;
  case 0 ... 9:
    return 3;
  default:
    return 7;
  }
}

static_assert(foo(-1) == 7, "");

When the above program is compiled with option -fexperimental-new-constant-interpreter enabled, it fails. When the option is disabled, it succeeds as expected.
