Clippy is now smarter about detecting unnecessary casts and
useless conversions, which means we need to be more explicit
about when the conversions are needed for a subset of platforms.
Required changes found by repeatedly running the following command
against a list of the supported platforms.
`xargs -t -I {} sh -c "cargo clippy -Zbuild-std --target {} --all-targets -- -D warnings || exit 255"`
I removed the casts it complained about, and then restored them
with an `#[allow]` if a later target needed the cast.
