Subject: [PATCH] [Clang] Fix build with GCC 14 on ARM (#78704)
GCC 14 defines `__arm_streaming` as a macro expanding to
`[[arm::streaming]]`. Due to the nested macro use, this gets expanded
prior to concatenation.
It doesn't look like C++ has a really clean way to prevent macro
expansion. The best I have found is to use `EMPTY ## X` where `EMPTY` is
an empty macro argument, so this is the hack I'm implementing here.
Fixes https://github.com/llvm/llvm-project/issues/78691.
