Duncan P. N. Exon Smith 6037e199c8 CodeGen: Turn on sentinel tracking for MachineInstr iterators

This is a prep commit before fixing MachineBasicBlock::reverse_iterator
invalidation semantics, ala r281167 for ilist::reverse_iterator.  This
changes MachineBasicBlock::Instructions to track which node is the
sentinel regardless of LLVM_ENABLE_ABI_BREAKING_CHECKS.

There's almost no functionality change (aside from ABI).  However, in
the rare configuration:

    #if !defined(NDEBUG) && !defined(LLVM_ENABLE_ABI_BREAKING_CHECKS)

the isKnownSentinel() assertions in ilist_iterator<>::operator* suddenly
have teeth for MachineInstr.  If these assertions start firing for your
out-of-tree backend, have a look at the suggestions in the commit
message for r279314, and at some of the commits leading up to it that
avoid dereferencing the end() iterator.
