Xun Li 516803dc86 [Coroutines] Ensure co_await promise.final_suspend() does not throw ... Summary: This patch addresses https://bugs.llvm.org/show_bug.cgi?id=46256 The spec of coroutine requires that the expression co_­await promise.final_­suspend() shall not be potentially-throwing. To check this, we recursively look at every call (including Call, MemberCall, OperatorCall and Constructor) in all code generated by the final suspend, and ensure that the callees are declared with noexcept. We also look at any returned data type that requires explicit destruction, and check their destructors for noexcept. This patch does not check declarations with dependent types yet, which will be done in future patches. Updated all tests to add noexcept to the required functions, and added a dedicated test for this patch. This patch might start to cause existing codebase fail to compile because most people may not have been strict in tagging all the related functions noexcept.
