Justin Bogner 9c6818ef00 InstrProf: Update for LLVM API change 
We've added support for a multiple functions with the same name in
LLVM's profile data, so the lookup returning the function hash it
found doesn't make sense anymore. Update to pass in the hash we
expect.

This also adds a test that the version 1 format is still readable,
since the new API is expected to handle that.

README 

These are tests for instrumentation based profiling.  This specifically means
the -fprofile-instr-generate and -fprofile-instr-use driver flags.

Tests in this directory should usually test both:

  - the generation of instrumentation (-fprofile-instr-generate), and
  - the use of profile data from instrumented runs (-fprofile-instr-use).

In order to test -fprofile-instr-use without actually running an instrumented
program, .profdata files are checked into Inputs/.

The input source files must include a main function such that building with
-fprofile-instr-generate and running the resulting program generates the same
.profdata file that is consumed by the tests for -fprofile-instr-use.  Even
tests that only check -fprofile-instr-use should include such a main function,
so that profile data can be regenerated as the .profdata file format evolves.
