[cfe-commits] [PATCH] Fix cleanups for while() statements

[Douglas Gregor]

This patch addresses various problems with cleanups for while statements. In particular:

1) It makes sure that we destroy the condition variable of a while statement each time through the loop for, e.g.,

	while (shared_ptr<WorkInt> p = getWorkItem()) {
		// ...
	}

2) It makes sure that we always enter a new cleanup scope for the body of the while loop, even when there is no compound expression, e.g.,

	while (blah)
	  RAIIObject raii(blah+1);

Daniel or Anders, please review the CodeGen changes in CGStmt.

	- Doug
