doh: fix undefined behaviour and open up for gcc and clang optimization
The undefined behaviour is annoying when running fuzzing with
sanitizers. The codegen is the same, but the meaning is now not up for
dispute. See https://cppinsights.io/s/516a2ff4
By incrementing the pointer first, both gcc and clang recognize this as
a bswap and optimizes it to a single instruction. See
https://godbolt.org/z/994Zpx
Closes #4350
