Summary: This patch adds processing of binary operations when the def of operands are in the same block (i.e. local processing). Earlier we bailed out in such cases (the bail out was introduced in rL252032) because LVI at that time was more precise about context at the end of basic blocks, which implied local def and use analysis didn't benefit CVP. Since then we've added support for LVI in presence of assumes and guards. The test cases added show how local def processing in CVP helps adding more information to the ashr, sdiv, srem and add operators. Note: processCmp which suffers from the same problem will be handled in a later patch.
