[PATCH] D30265: [APInt] Add APInt::setBits() method to set all bits in range

[Simon Pilgrim via Phabricator via llvm-commits]

RKSimon updated this revision to Diff 89509.
RKSimon added a comment.

Dropped the wrap around functionality as it doesn't appear to have many use cases - and makes it easier to drop in as a replacement for APInt::getLowBitsSet/getHighBitsSet.

Removed use of APInt::setBit and do everything at the word level instead.

Added extra test cases that should cover all mask permutations.
