that appear in the SCC as a result of inlining as candidates
for inlining.  Change this so that it *does* consider call 
sites that change from being indirect to being direct as a
result of inlining.  This allows it to completely 
"devirtualize" the testcase.

arguments are handled with a new InlineFunctionInfo class.  This 
makes it easier to extend InlineFunction to return more info in the
future.

define void @f3(void (i8*)* %__f) ssp {
entry:
  call void %__f(i8* undef)
  unreachable
}

define void @f4(i8* %this) ssp align 2 {
entry:
  call void @f3(void (i8*)* @f2) ssp
  ret void
}

The inliner is turning the indirect call to %__f into a direct
call to F2.  Make the call graph more precise when this happens.

The inliner doesn't revisit call sites introduced by inlining,
so there isn't an easy way to test for this, but a more precise
callgraph is a good thing.

simplify the second copy of the loop which may be dead or not,
but is probably a constant now.  This fixes PR6879

Arg promotion was deleting call graph nodes that still had references
from the 'indirect' CGN.  Like the inliner, it should only delete the
function if all references are gone.

just ask ScalarEvolution for it on demand. This helps IVUsers be more robust

to determine where to place PHIs by iteratively comparing reaching definitions
at each block.  That was just plain wrong.  This version now computes the
dominator tree within the subset of the CFG where PHIs may need to be placed,
and then places the PHIs in the iterated dominance frontier of each definition.
The rest of the patch is mostly the same, with a few more performance
improvements added in.

Probably the best way to know that all getOperand() calls have been handled
is to replace that API instead of updating.

but now we have a much tidier interface.

more efficient access to operands and callee, faster callgraph-construction,
smaller compiler binary
