Diego Novillo e75c2b3e54 Add profile writing capabilities for sampling profiles. ... Summary: This patch finishes up support for handling sampling profiles in both text and binary formats. The new binary format uses uleb128 encoding to represent numeric values. This makes profiles files about 25% smaller. The profile writer class can write profiles in the existing text and the new binary format. In subsequent patches, I will add the capability to read (and perhaps write) profiles in the gcov format used by GCC. Additionally, I will be adding support in llvm-profdata to manipulate sampling profiles. There was a bit of refactoring needed to separate some code that was in the reader files, but is actually common to both the reader and writer. The new test checks that reading the same profile encoded as text or raw, produces the same results.
