[PATCH] D151683: [clang] Enable C++11-style attributes in all language modes

Hi,

Is it a known issue, that clang doesn't compile `void foo(char *argv[] [[maybe_unused]]) {}` ?

https://godbolt.org/z/r9E81cWxh - clang fails, but gcc doesn't.

It looks like there is a lot of oss code of the form `void foo(char *argv[] ATTRIBUTE_UNUSED)`, where `ATTRIBUTE_UNUSED` was configured to `__attribute__((unused))` before this change (thus compiled ok) and to `[[maybe_unused]]` after this change (thus started to break).
