Bug 1369622 - Restore static asserts for lack of arguments on some macros. r=froydnj Bug 1368932 removed MOZ_STATIC_ASSERT_VALID_ARG_COUNT because it didn't actually work for large numbers of arguments. But it was kind of useful for macros that expand to something broken when they are given no variadic argument at all. Now that we have a macro that doesn't require tricks to count empty arguments lists, however, we can use straightforward static_asserts instead of a generic macro, which has the side effect of providing more context in the error message.
