In most calling conventions, accessing function parameters may require
stack access. However, naked functions have no assembly prelude to set
up stack access. This is why naked functions may only contain a single
`asm!()` block. All parameter access is done inside the `asm!()` block,
so we cannot validate the liveness of the input parameters. Therefore,
we should disable the lint for naked functions.
