Summary:
In a recent commit, we changed local symbols to be specially tagged
with the number 2 (local sym) instead of 1 (sym). This patch modifies the reader
to don't choke when seeing a 2 in the symbol id field.
(cherry picked from FBD2552776)
Summary:
Changes DataReader to organize branch perf data per function name and
sets up logistics to bring this data to BinaryFunction::buildCFG(). To do this,
we expand BinaryContext with a const reference to DataReader. This patch also
adds the "-dump-functions" flag to force llvm-flo to dump the current state of
BinaryFunctions once they are disassembled and their CFG built, allowing us to
test whether the builder is sane with LLVM LIT tests.

Summary:
This patch introduces DataReader, a module responsible for
parsing llvm flo data files into in-memory data structures.
