  -----------
  Remove loop strength reduction because WasmAddress broke it.
https://bugs.webkit.org/show_bug.cgi?id=243178

Reviewed by Yusuke Suzuki.

When WasmAddress was added, it broke this pass. We should eventually fix it,
but for now we should remove it since it never actually gets applied.
