a8bd65835b Refactor memcpyopt based on Chris' suggestions. Consolidate several functions 
and simplify code that was fallout from the separation of memcpyopt and gvn.

54b9c3ba2a Move SplitBlockPredecessors out of loopsimplify into BasicBlockUtils.h 
as a global helper function.  At the same type, switch it from taking
a vector of predecessors to an arbitrary sequential input.  This allows
us to switch LoopSimplify to use a SmallVector for various temporary
vectors that it passed into SplitBlockPredecessors.

eee962e1ce Teach InstCombine's ComputeMaskedBits to handle pointer expressions 
in addition to integer expressions. Rewrite GetOrEnforceKnownAlignment
as a ComputeMaskedBits problem, moving all of its special alignment
knowledge to ComputeMaskedBits as low-zero-bits knowledge.

Also, teach ComputeMaskedBits a few basic things about Mul and PHI
instructions.

This improves ComputeMaskedBits-based simplifications in a few cases,
but more noticeably it significantly improves instcombine's alignment
detection for loads, stores, and memory intrinsics.

3d292aca03 The "stacksave is not nounwind problem" no longer

that intrinsics always get the right attributes.

Intrinsic::getDeclaration rather than getOrInsertFunction.
