Veronika Molnarova 06a130e42a perf test: Handle perftool-testsuite_probe failure due to broken DWARF 
Test case test_adding_blacklisted ends in failure if the blacklisted
probe is of an assembler function with no DWARF available. At the same
time, probing the blacklisted function with ASM DWARF doesn't test the
blacklist itself as the failure is a result of the broken DWARF.

When the broken DWARF output is encountered, check if the probed
function was compiled by the assembler. If so, the broken DWARF message
is expected and does not report a perf issue, else report a failure.  If
the ASM DWARF affected the probe, try the next probe on the blacklist.
If the first 5 probes are defective due to broken DWARF, skip the test
case.

Fixes: def5480d63 ("perf testsuite probe: Add test for blacklisted kprobes handling")
