[PATCH] D142279: [cmake] Use LLVM_ENABLE_ASSERTIONS to enable assertions in libstdc++

I've investigated a bit more. It's a difference between libstdc++-11 and libstdc++-12, caused by this patch:

https://gcc.gnu.org/git/gitweb.cgi?p=gcc.git;h=a54ce8865a885bca5ab9c4aa6ec725cd13c09901

Previously a failed assertion would print a message with __builtin_printf. Now it prints a message by calling __glibcxx_assert_fail which is defined in the library.

What's the way forward for the flang runtime library? Can we disable libstdc++ assertions? Can we provide our own implementation of __glibcxx_assert_fail?
