[PATCH] D45784: [DEBUG_INFO, NVPTX] Fix relocation info.

[Alexey Bataev via llvm-commits]

It requires .loc directive with fileref, line number and column number.
Seems to me, line number and column number can be zeroed.

The function starting label is used to evaluate function relocation info
and without this .loc directive the relocation info is incorrect. I
can't say why it requires this directive for the initial label. All
other labels inherit their location from the first following
instruction, but not the very first one.

-------------
Best regards,
Alexey Bataev
