25e681ac22 CallGraphSCCPass manager may require other passes. 
Use schedulePass() to accomodate these requirement instead of directly
assigning a manager to new CallGraph PassManager.

5cec4db6ae Rename ScalarEvolution::deleteInstructionFromRecords to 
deleteValueFromRecords and loosen the types to all it to accept
Value* instead of just Instruction*, since this is what
ScalarEvolution uses internally anyway. This allows more flexibility
for future uses.

f50cd749e1 In SCEVAddExpr::get, skip over any cast operands before looking for nested 
add operands after constant operands. The recent change to recognize
sign-extend expressions caused this to be exposed more often.

d19534add9 Add a SCEV class and supporting code for sign-extend expressions. 
This created an ambiguity for expandInTy to decide when to use
sign-extension or zero-extension, but it turns out that most of its callers
don't actually need a type conversion, now that LLVM types don't have
explicit signedness. Drop expandInTy in favor of plain expand, and change
the few places that actually need a type conversion to do it themselves.

static const int, which defauts PassID based pass identification.
