Here is a testcase which clang accepts but GCC rejects:
int b;
int e;
#define a(...) b /##__VA_OPT__(c) e
int y = a();

libcpp: Fix up ##__VA_OPT__ handling [PR89971]
In the following testcase we incorrectly error about pasting / token
with padding token (which is a result of __VA_OPT__); instead we should
like e.g. for ##arg where arg is empty macro argument clear PASTE_LEFT
flag of the previous token if __VA_OPT__ doesn't add any real tokens
(which can happen either because the macro doesn't have any tokens
passed to ... (i.e. __VA_ARGS__ expands to empty) or when __VA_OPT__
doesn't have any tokens in between ()s).
