Cleanup the current binary testcase for profile data.
- Rename it to something more specific.
- Remove the text comparison.
- Check the output of llvm-profdata show.
llvm-svn: 204518
Read a raw binary profile that corresponds to a memory dump from the
runtime profile.
The test is a binary file generated from
cfe/trunk/test/Profile/c-general.c with the new compiler-rt runtime and
the matching text version of the input. It includes instructions on how
to regenerate.

Chandler voiced some concern with checking this in without some
discussion first. Reverting for now.
This reverts r203703, r203704, r203708, and 203709.

This replaces the llvm-profdata tool with a version that uses the
recently introduced Profile library. The new tool has the ability to
generate and summarize profdata files as well as merging them.

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.
