[PATCH] D136822: [InstCombine] Allow memcpys from constant memory to readonly noalias parameters to be elided.

[Nikita Popov via Phabricator via llvm-commits]

By the way, the asan test failure in printf-5.c may be legitimate. Sometimes, this kind of change ends up optimizing away the code causing the asan failure. In that case it's necessary to adjust the test case to prevent the optimization.
