[PATCH] D15306: [llvm-profdata] Add support for weighted merge of profile data (2nd try)

[Nathan Slingerland via llvm-commits]

I still think a check is a good idea for the edge case mentioned above (input contains ':' but is not specifying a weight and does not exist) so that the error message is correct. But thankfully I think since sys::fs::exists() works we can just check if the split path exists - if it doesn't fall back to default behavior. Hopefully that's a more appealing way to do this.
