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.
