Introducing llvm-profdata, a tool for merging profile data generated by PGO instrumentation in clang. - The name indicates a file extension of <name>.profdata. Eventually profile data output by clang should be changed to that extension. - llvm-profdata merges two profiles. However, the name is more general, since it will likely pick up more tasks (such as summarizing a single profile). - llvm-profdata parses the current text-based format, but will be updated once we settle on a binary format. <rdar://problem/15949645> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@201535 91177308-0d34-0410-b5e6-96231b3b80d8
