Perform partial array destruction as if in an EH cleanup. Unlike emitArrayDestroy, the element type here may still be an array type.

emitStoresForInitAfterMemset - For inits that canEmitInitWithFewStoresAfterMemset returned true for, emit the scalar stores that would be required.

hasNontrivialDestruction - Determine whether a type's destruction is non-trivial. If so, and the variable uses static initialization, we must register its destructor to run on exit.

shouldUseMemSetPlusStoresToInitialize - Decide whether we should use memset plus some stores to initialize a local variable instead of using a memcpy from a constant global. It is beneficial to use memset if the global is all zeros, or mostly zeros and large.
