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.
