d411ac1267 Load / store multiple was missing opportunites when the load / store bundles are at the end of the bb. Test case is already in, the bug is exposed by subsequent commit.

3fb4c19b7d move 'loading i32 from string' optimization from instcombine
to libanalysis.  Instcombine shrinking... does this even 
make sense???

2c8c8533b1 Move some constant folding logic for loads out of instcombine into
Analysis/ConstantFolding.cpp.  This doesn't change the behavior of
instcombine but makes other clients of ConstantFoldInstruction
able to handle loads.  This was partially extracted from Eli's patch
in PR3152.

2d8e5654a8 Revert the main portion of r31856. It was causing BranchFolding
to break up CFG diamonds by banishing one of the blocks to the end of
the function, which is bad for code density and branch size.

This does pessimize MultiSource/Benchmarks/Ptrdist/yacr2, the
benchmark cited as the reason for the change, however I've examined
the code and it looks more like a case of gaming a particular
branch than of being generally applicable.

0996619220 Make changes to rev 84292 as requested by Chris Lattner.
Most changes are cleanup, but there is 1 correctness fix:
I fixed InstCombine so that the icmp is removed only if the malloc call is removed (which requires explicit removal because the Worklist won't DCE any calls since they can have side-effects).

- i < getNumElements()  instead of getNumElements() > i
- Make setParent() private
- Fix use of resizeOperands
- Reset HasMetadata bit after removing all metadata attached to an instruction
- Efficient use of iterators
