Namhyung Kim a104f0ea99 perf test: Add 'brstack' test workload 
The brstack is to run different kinds of branches repeatedly.  This is
necessary for brstack test case to verify if it has correct branch info.

  $ perf test -w brstack

I renamed the internal functions to have brstack_ prefix as it's too
generic name.

Add a -U_FORTIFY_SOURCE to the brstack CFLAGS, as the main perf flags
set it and it requires building with optimization, and this new test has
a -O0.
