Of the 128-bits of buffer descriptor only 48 bits are address bits, so following the discussion on https://discourse.llvm.org/t/clarifiying-the-semantics-of-ptrtoint/83987/54, the logic conclusion is to set the index width to 48 bits instead of the current value of 128. Most of the test changes are mechanical datalayout updates, but there is one actual change: the ptrmask test now uses .i48 instead of .i128 and I had to update SelectionDAGBuilder to correctly extend the mask.
