vectors of all one bits to be printed more cleverly in the AsmPrinter. Unfortunately, the byte value for all one bits is the same with -fsigned-char as the error return of '-1'. Force this to be the unsigned byte value when returning it to avoid this problem, and update the test case for the shiny new behavior. Yay for building LLVM and Clang with -funsigned-char. Chris, please review, and let me know if there is any reason to not desire this change. It seems good on the surface, and certainly intended based on the code written. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@149299 91177308-0d34-0410-b5e6-96231b3b80d8
