Previously, clang was crashing on the attached test because the EH cleanup for the block capture was incorrectly emitted under the assumption that the expression wasn't conditionally evaluated. This was because before 9a52de00260, pushLifetimeExtendedDestroy was mainly used with C++ automatic lifetime extension, where a conditionally evaluated expression wasn't possible. Now that we're using this path for block captures, we need to handle this case. rdar://66250047 Differential revision: https://reviews.llvm.org/D86854
