[PATCH] D30563: [APInt] Implement getLowBitsSet/getHighBitsSet/getBitsSet using setLowBits/setHighBits/setBits

[Craig Topper via Phabricator via llvm-commits]

craig.topper created this revision.

This patch implements getLowBitsSet/getHighBitsSet/getBitsSet in terms of the new setLowBits/setHighBits/setBits methods by making an all 0s APInt and then calling the appropriate set method.

This also adds support to setBits to allow loBits/hiBits to be in the other order to match with getBitsSet behavior.
