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

[Nathan Slingerland via llvm-commits]

>From the end user's perspective the <filename>:<weight> syntax seems the most intuitive and concise. And no matter what delimiter we choose (even with a separate option) there will still be edge cases for us to differentiate between file names containing ',' and the user trying but failing to specify a weight.
