ad772bfec3 Change the interface to SCEVExpander::InsertCastOfTo to take a cast opcode 
so the decision of which opcode to use is pushed upward to the caller.
Adjust the callers to pass the expected opcode.

9c52dc6c34 Change the implementation of statistic to not need destructors at all. 
Instead, the stat info is printed when llvm_shutdown() is called.
These also don't need static ctors, but getting rid of them is uglier:
still investigating.  This reduces the number of static dtors in llvm from
~1400 to ~750.

19cb81393d For PR950: 
Remove the getMaxValue and getMinValue functions from ConstantIntegral.
They don't make sense for a signless type. Also, for isMaxValue and

it from the constant's type.

       DOUT << "This is a status line: " << Var << "\n";

If "-debug" is specified, it will print. Otherwise, it'll not print. If
NDEBUG is defined, the DOUT does nothing.
