[Bug c++/93314] Invalid use of non-static data member causes ICE in gimplify_expr

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=93314 --- Comment #1 from Language Lawyer --- GCC thinks that `char[S::m]` is VLA (because the lvalue-to-rvalue conversion on `S::m` lvalue doesn't look like a constant expression) and tries to move the evaluation of `sizeof(char[S::m])` to run time.
