[PATCH] D31669: Fix lambda to block conversion in C++17 by avoiding copy elision for the lambda capture used by the created block

[Alex Lorenz via Phabricator via cfe-commits]

arphaman created this revision.

The commit r288866 introduced guaranteed copy elision to C++ 17. This unfortunately broke the lambda to block conversion in C++17 (the compiler crashes when performing IRGen). This patch fixes the conversion by avoiding copy elision for the capture that captures the lambda that's used in the block created by lambda to block conversion process.
