The work on this project was left in an unfinished and inconsistent state. Hopefully someone will eventually get a chance to implement this feature, but in the meantime, it is better to put things back the way the were. I have left support in the bitcode reader to handle the case-range bitcode format, so that we do not lose bitcode compatibility with the llvm 3.3 release. This reverts the following commits: 155464, 156374, 156377, 156613, 156704, 156757, 156804 156808, 156985, 157046, 157112, 157183, 157315, 157384, 157575, 157576, 157586, 157612, 157810, 157814, 157815, 157880, 157881, 157882, 157884, 157887, 157901, 158979, 157987, 157989, 158986, 158997, 159076, 159101, 159100, 159200, 159201, 159207, 159527, 159532, 159540, 159583, 159618, 159658, 159659, 159660, 159661, 159703, 159704, 160076, 167356, 172025, 186736 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@190328 91177308-0d34-0410-b5e6-96231b3b80d8
