not folded in the constant folder because the constant folder doesn't

d219c7b6ee add a new CallGraphNode::replaceCallEdge method and use it from 
argpromote to avoid invalidating an iterator.  This fixes PR4977.
All clang tests now pass with expensive checking (on my system 
at least).

aa66e3d968 Teach lib/VMCore/ConstantFold.cpp how to set the inbounds keyword and 
how to fold notionally-out-of-bounds array getelementptr indices instead
of just doing these in lib/Analysis/ConstantFolding.cpp, because it can
be done in a fairly general way without TargetData, and because not all
constants are visited by lib/Analysis/ConstantFolding.cpp. This enables
more constant folding.

Also, set the "inbounds" flag when the getelementptr indices are
one-past-the-end.

14bc5768e0 Fixed wrong storage option for ProfileVerifierDisableAssertions. 
Fixed non working -profile-verifier-noassert option.
Fixed missing newline in debugEntry().
Cleaned up assert messages. (assert(0 && Message) is still shown, but the message is printed before.)
When verifiying loaded profiles the ProfileVerifier got confused when block was a setjmp target, this is checked now.
When verifiying loaded profiles the ProfileVerifier got confused when block eventually reaching an exit(), this is checked now.

cdaa08e706 Re-apply r80926, with fixes: keep the domtree informed of new blocks 
that get created during loop unswitching, and fix SplitBlockPredecessors'
LCSSA updating code to create new PHIs instead of trying to just move
existing ones.

Also, optimize Loop::verifyLoop, since it gets called a lot. Use
searches on a sorted list of blocks instead of calling the "contains"
function, as is done in other places in the Loop class, since "contains"
does a linear search. Also, don't call verifyLoop from LoopSimplify or
LCSSA, as the PassManager is already calling verifyLoop as part of
LoopInfo's verifyAnalysis.

357614a0ca Do not try to override non-virtual methods, especially 
when the new method gives the same result as the original
(as far as I can see).  This will hopefully pacify icc.

e5ec3c1a26 Remove the API for creating ConstantExprs with the nsw, nuw, inbounds, 
and exact flags. Because ConstantExprs are uniqued, creating an
expression with this flag causes all expressions with the same operands
to have the same flag, which may not be safe. Add, sub, mul, and sdiv
ConstantExprs are usually folded anyway, so the main interesting flag
here is inbounds, and the constant folder already knows how to set the
inbounds flag automatically in most cases, so there isn't an urgent need
for the API support.

This can be reconsidered in the future, but for now just removing these
API bits eliminates a source of potential trouble with little downside.
