yurys@chromium.org 44dfaa2a1e Fix test-cpu-profiler/FunctionCallSample flakiness under GC stress testing ... The test flakes on "V8 GC Stress" bots and the sample looks like this: [Top down]: 90 0 (root) [-1] #0 1 1 1 (program) [-1] #0 2 89 89 (garbage collector) [-1] #0 3 which means that almost all samples are inside GC and we have no |start| node in the collected profile. Running the test with different combinations of --gc-interval=500 and --stress-compaction flags gives the results quoted below. They don't give a ground to require |start| node presense in the profile when doing GC stress testing. So this change makes the |start| node optional in the collected profile if GC stress testing is on. $ ./out/ia32.debug/cctest --gc-interval=500 --stress-compaction --trace-gc test-cpu-profiler/FunctionCallSample [10291] 76 ms: Mark-sweep 0.5 (17.8) -> 0.4 (17.8) MB, 49.5 ms (+ 0.2 ms in 1 steps since start of marking, biggest step 0.2 ms) [StackGuard GC request] [GC in old space requested].
