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.

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.

select the "important" subregion of the source line, which contains
everything that we want to show (e.g., with underlining and the caret
itself) and tries to also contain some of the context. 

From the fantastically long line in the test case, we get an error
message that slices down to this:

message-length.c:18:120: warning: comparison of distinct pointer types
      ('int *' and 'float *')
  a_func_to_call(ip == FloatPointer, ip[ALongIndexName], 
                 ~~ ^  ~~~~~~~~~~~~

There are a bunch of gee-it-sounds-good heuristics in here, which seem
to do well on the various simple tests I've thrown at it. However,
we're going to need to look at a bunch more diagnostics to tweak these
heuristics.

This is the second part of <rdar://problem/6711348>. Almost there!
