Meador Inge 32dc724920 ADT: Correct APInt::getActiveWords for zero values ... PR15138 was opened because of a segfault in the Bitcode writer. The actual issue ended up being a bug in APInt where calls to APInt::getActiveWords returns a bogus value when the APInt value is 0. This patch fixes the problem by ensuring that getActiveWords returns 1 for 0 valued APInts. llvm-svn: 174641		2013-02-07 18:36:50 +00:00
