This reverts commit r221842 which was a revert of r221836 and of the test parts of r221837. This new version fixes an UB bug pointed out by David (along with addressing some other review comments), makes some dumping more resilient to broken input data and forces the accelerator tables to be dumped in the tests where we use them (this decision is platform specific otherwise). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@222003 91177308-0d34-0410-b5e6-96231b3b80d8
