D62502, together with D62503 have broken the builds which have XML support enabled. Reverting D62503 (r364355) fixed that, but has broken has left some of the tests introduced by D62502 broken more or less nondeternimistically (it depended on whether the system happens to place the library list near unreadable pages of memory). I attempted to make a partial fix for this in r364748, but Jan Kratochvil pointed out that this reintroduces the problem which reverting D62503 was trying to solve. So instead, I back out the whole thing so we can get back to a clean slate that works for everyone. We can figure out a way forward from there. This reverts r364748, r363772 and r363707. llvm-svn: 364751
