[llvm-branch-commits] [NFC][TSan] Check IsFiredSuppression before ScopedReport in ReportErrnoSpoiling (PR #228811)

[Vitaly Buka via llvm-branch-commits]

Check IsFiredSuppression(ctx, ReportTypeErrnoInSignal, stack) and return
early before constructing ScopedReport in ReportErrnoSpoiling (matching
SignalUnsafeCall and ReportRace). This avoids acquiring
ScopedErrorReportLock and ThreadRegistryLock for already-suppressed
reports.
