Duncan P. N. Exon Smith 24b4b65339 InstrProf: Read raw binary profile in llvm-profdata 
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.

Justin Bogner f8d791983c ProfileData: Introduce the InstrProfReader interface and a text reader 
This introduces the ProfileData library and updates llvm-profdata to
use this library for reading profiles. InstrProfReader is an abstract
base class that will be subclassed for both the raw instrprof data
from compiler-rt and the efficient instrprof format that will be used
for PGO.
