  Log Message:
  -----------
  [MC,NVPTX] Add MCAsmPrinter support for unsigned-only data directives.

PTX does not support negative values in .bNN data directives and we must
typecast such values to unsigned before printing them.

MCAsmInfo can now specify whether such casting is necessary for particular
target.
