Change Details

Initial changes in interfaces of MCAsmStreamer/MCTargetStreamer for correct debug info emission for Cuda. 1. PTX foramt does not support `.ascii` directives. Added the ability to nullify it. 2. DWARF `.loc` directives must be emitted after `.text` section and cannot be inlined in function bodies. 3. The initial function label must follow the first debug `.loc` directive, not be followed by. 4. DWARF sections must be enclosed in braces.
