[cfe-dev] if (p == nullptr) style conventions?

[Richard]

Does LLVM/clang have any style convention preferring:

if (p)

over

if (p != nullptr)

?

or it's converse:

if (!p)

over

if (p == nullptr)

?

I didn't find anything in the existing style guide and I've gotten
a request for readability-simplify-boolean-expr in clang-tidy to
make such simplifications.
