Changes in directory llvm/include/llvm:
Constants.h updated: 1.135 -> 1.136
---
Log message:
Add an isUnitValue method for comparison against 1. This just follows a
common pattern with isNullValue, isAllOnesValue, etc. It also helps to
prevent things like getZExtValue() == 1, which could assert for large
bitwidths.
