*	[CodeGen] Eagerly emit lifetime.end markers for calls	George Burgess IV	2018-03-10	1	-0/+101
	In C, we'll wait until the end of the scope to clean up aggregate temporaries used for returns from calls. This means in cases like: { // Assuming that `Bar` is large enough to warrant indirect returns struct Bar b = {}; b = foo(&b); b = foo(&b); b = foo(&b); b = foo(&b); } ...We'll allocate space for 5 Bars on the stack (`b`, and 4 temporaries). This becomes painful in things like large switch statements. If cleaning up sooner is trivial, we should do it. llvm-svn: 327229
