crc32: add notw macro
...
instead of materializing a constant 0xffffffff, do a NOT and then
zero-extend the result. my qemu doesn't support the zext.w instruction,
so we have to do two shifts instead. these can potentially be fused
into a single instruction by the processor.

env: use writev to add the newline
...
this allows us to print each line in a single, atomic write call,
without modifying or buffering it.

they're so small it doesn't really matter; better to keep them simple.
