Fix the generated code when `lto=true`

[greenhat]

From #1065

6. lto=true is super interesting. It gives the most significant (50%-90%) decrease in size but the compiled code no longer works (47 tests failed). I want to dig into it more. I've checked the basic-walled contract code and besides very aggressive inlining where compiler/sdk/base-sys/src/bindings/native_account.rs was inlined with most of the glue code optimized away.
