Changes in directory llvm/lib/VMCore:

Type.cpp updated: 1.161 -> 1.162
---
Log message:

Provide an isPowerOf2ByteWidth method for the IntegerType class. This will
mostly be used by back ends that wish to distinguish between integer types
that fit evenly within a natural integer type and those that don't.
