Changes in directory llvm/include/llvm:
Constants.h updated: 1.107 -> 1.108
---
Log message:
Fix problems in the CBE and InstructionCombining which use the isMaxValue
and isMinValue methods of ConstantInt. These have been broken since the
isSigned parameter was added. It is necessary to use the signed version
of the type in the call to isValueValidForType or else incorrect results
are returned.
