live as long as they needed to. This led to equality tests involving persistent variables often failing or succeeding when they had no business doing so. To do this, I introduced the ability for a memory allocation to "leak" - that is, to persist in the process beyond the lifetime of the expression. Hand-declared persistent variables do this now. <rdar://problem/13956311> llvm-svn: 182528
