pchickey opened PR #1336 from pch/wiggle_tweaks_for_lucet to master:

• wiggle-generate: fix bug where it would panic on an anonymous array type
• a witx usize is a rust u32, not a rust usize. Rust isize and usize are not GuestTypes, because they have a different representation depending on the Rust host.
• always pass GuestPtr to the module trait methods by reference. This was inconsistent - would be reference for arrays and strings, but not for regular @witx pointer types.
