[libc] fix behavior of strrchr(x, '\0')
strrchr("foo", '\0') is defined to point to the end of foo, rather than returning NULL. This wasn't caught by tests, since llvm-libc's ASSERT_STREQ(nullptr, ""); is not an assertion error.
While I'm here, refactor the test slightly to check for NULL more specifically. I considered adding fancier ASSERTs (and changing the semantics of ASSERT_STREQ), but opted for a more local fix by fair dice roll.

Thanks for the patch! Yes, that's a bug!
I thought the nice thing about ASSERT_EQ or in this case ASSERT_STREQ is that when the assertion fails, it tells you what was expected vs what was observed (i.e. NULL vs 'a') rather than expected true, saw false? I think that kind of behavior is nice to retain.
Oh, I didn't realize that I missed this:

My mistake - I'll see what I can do :)
So, better response:

I tried to use ASSERT_EQ/ASSERT_NE, but ASSERT_NE("foo", nullptr) turns into an overload resolution error. I've updated my patch to allow ASSERT_{EQ,NE}(foo, nullptr). Alternatively
- can
static_cast<const char *>()around the nullptrs if that'd be preferred, - or I can add a second overload if llvm-libc doesn't have conventions around whether
nullptrconstants should go in the LHS or RHS positions

@gburgessiv I think you need to replace std::nullptr_t with cpp::nullptr_t from https://github.com/llvm/llvm-project/blob/main/libc/src/__support/CPP/type_traits/is_null_pointer.h#L20
(#include "src/__support/CPP/type_traits.h" should work).
