The goal here is to make it possible to display absolute file offsets when dumping byets from an MSF. The problem is that when dumping bytes from an MSF, often the bytes will cross a block boundary and encounter a discontinuity. We can't use the normal formatBinary() function for this because this would just treat the sequence as entirely ascending, and not account out-of-order blocks. This patch adds a formatMsfData() function to our printer, and then uses this function to improve the output of the -stream-data command line option for dumping bytes from a particular stream. Test coverage is also expanded to make sure to include all possible scenarios of offsets, sizes, and crossing block boundaries. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@306141 91177308-0d34-0410-b5e6-96231b3b80d8
