[clang-tidy] As a simple heuristic don't emit a swap fixit that would create
...
negative-sized memsets.
memset(x, -1, 0) is still useless but swapping makes no sense here. Just emit
a warning.

[clang-tidy] Also emit a warning for memset(x, 0, 0)
...
It doesn't make sense to suggest swapping the arguments here but it's
still useless code

[clang-tidy] Add a checker for zero-length memset.
...
If there's memset(x, y, 0) in the code it's most likely a mistake. The
checker suggests a fix-it to swap 'y' and '0'.
I think this has the potential to be promoted into a general clang warning
after some testing in clang-tidy.
