Constify most methods. We could have constified doInitialization and
doFinalization too except that would have made them shadow, not override, the parent class :-P. Allow *any* constant cast expression between pointers and longs, or vice-versa, or any widening (not just same-size) conversion that isLosslesslyConvertibleTo approves. This fixes oopack. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@7288 91177308-0d34-0410-b5e6-96231b3b80d8
