[JSC] Add strength reduction rules for WasmRefCast / WasmRefTest with
WasmStructNew
https://bugs.webkit.org/show_bug.cgi?id=306849
rdar://169516425
Reviewed by Sosuke Suzuki.
This patch adds simple strength reduction rules for
WasmRefCast(WasmStructNew) / WasmRefTest(WasmStructNew). We can just
obtain the type and fold them, and remove them potentially. This can
happen when you inline the other functions, or you are storing and
loading from wasm locals which have broader type.
