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.
