wasm linker: fix corruption of string bytes
...
if any fixups are emitted in lowering data, keep the string bytes
allocated even if all zeroes because it is used as a fixup staging area.

wasm linker: don't assume nav callees are fully resolved
...
codegen can be called which contains calls to navs which have only their
