[PATCH] D105491: [clang] Use i64 for the !srcloc metadata on asm IR nodes.

@lattner, thanks for the help. In this case, the real question is whether there's any use case for `!srcloc` that involves writing it out into a bitcode or IR file and then having a separate instance of clang load it back in again.

I think that no such case can possibly give a useful mapping back to the original source, because IR doesn't serialise the SourceManager that knows how to turn source locations back into a useful error message.
