db6fa29641 Convert ScalarEvolution to use CallbackVH for its internal map. This
makes ScalarEvolution::deleteValueFromRecords, and it's code that
subtly needed to be called before ReplaceAllUsesWith, unnecessary.

It also makes ValueDeletionListener unnecessary.

e66f6f15e6 The second argument to RecursivelyDeleteTriviallyDeadInstructions has
a default value, and will hopefully be going away soon.


git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@70642 91177308-0d34-0410-b5e6-96231b3b80d8

afc36a9520 Previously, RecursivelyDeleteDeadInstructions provided an option
of returning a list of pointers to Values that are deleted. This was
unsafe, because the pointers in the list are, by nature of what
RecursivelyDeleteDeadInstructions does, always dangling. Replace this
with a simple callback mechanism. This may eventually be removed if
all clients can reasonably be expected to use CallbackVH.

Use this to factor out the dead-phi-cycle-elimination code from LSR
utility function, and generalize it to use the
RecursivelyDeleteTriviallyDeadInstructions utility function.

This makes LSR more aggressive about eliminating dead PHI cycles;
adjust tests to either be less trivial or to simply expect fewer
instructions.

fb7d35f22a When ScalarEvolution is told to forget the trip count for a loop, have
it also forget any SCEVs associated with loop-header PHIs in the loop,
as they may be dependent on trip count information.

9a936502fa Tell ScalarEvolution that the loop is being deleted before actually
deleting it.  This will let ScalarEvolution be more complete about
updating its records.

1dcad96dc6 Don't split critical edges during the AddUsersIfInteresting phase
of LSR. This makes the AddUsersIfInteresting phase of LSR a pure
analysis instead of a phase that potentially does CFG modifications.

The conditions where this code would actually perform a split are
rare, and in the cases where it actually would do a split the split
is usually undone by CodeGenPrepare, and in cases where splits
actually survive into codegen, they appear to hurt more often than
they help.
