Enable local variable dead store elimination If a variable can not escape the function, we mark the store to it as dead before the function exits. It was disabled due to some TBAA and side-effect analysis changes. We were removing 8 dead stores on the stdlib. With this change, we are now removing 203 dead stores. I only see noise-level performance difference on PerfTestSuite. I do not see real increase on compilation time either.
