[wasm] Add a test to inspect a large number of registers
This tests inspecting a bigger number of registers (covers all registers on many platforms). It also executes all four intrinsic types (i32, i64, f32, f64). R=thibaudm@chromium.org Bug: v8:10222 Change-Id: I340696d525e4001f241bb22f62f0338018ad9804 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2102575 Commit-Queue: Clemens Backes <clemensb@chromium.org> Reviewed-by: Thibaud Michaud <thibaudm@chromium.org> Cr-Commit-Position: refs/heads/master@{#66720}
