perf test: Add 'datasym' test workload
The datasym workload is to check if perf mem command gets the data
addresses precisely. This is needed for data symbol test.
$ perf test -w datasym
I had to keep the buf1 in the data section, otherwise it could end
up in the BSS and was mmaped as a separate //anon region, then it
was not symbolized at all. It needs to be fixed separately.
Committer notes:
Add a -U _FORTIFY_SOURCE to the datasym CFLAGS, as the main perf flags
set it and it requires building with optimization, and this new test has
a -O0.
