This commit also replaces `.get_unchecked(0)` with `.as_ptr()` (when
casting slice to typed object), which makes MIRI slightly happier (in
previous approach, the pointer was valid only for the first byte) – in
fact, it now passes tests with following flags:
env MIRIFLAGS='-Zmiri-disable-alignment-check -Zmiri-disable-validation -Zmiri-tag-raw-pointers' \
cargo miri test
