generalizing the bswap detection to track bits instead of bytes might be a way
to handle this (there's the related issue of us failing to "copy propagate"
bits
with the associated possible simplifications

PS: I've just stumbled upon the more generic case, which would be this code:
unsigned int stb_bitreverse(unsigned int n)
{
n = ((n & 0x) >> 1) | ((n & 0x) << 1);
n = ((n & 0x)
