Remove many references to ASTContext::getAllocator(), replacing them with calls to the recently added placement new (which uses ASTContext's allocator for memory). Also added ASTContext::Deallocate().

This will simplify runtime replacement of ASTContext's allocator. Keeping the allocator private (and removing getAllocator() entirely) is also goodness.
