Joachim Protze	3c76e99291	[OpenMP] Fix deadlock for detachable task with child tasks This patch fixes https://bugs.llvm.org/show_bug.cgi?id=49066. For detachable tasks, the assumption breaks that the proxy task cannot have remaining child tasks when the proxy completes. In stead of increment/decrement the incomplete task count, a high-order bit is flipped to mark and wait for the incomplete proxy task.

[OpenMP] Fix deadlock for detachable task with child tasks

This patch fixes https://bugs.llvm.org/show_bug.cgi?id=49066.

For detachable tasks, the assumption breaks that the proxy task cannot have
remaining child tasks when the proxy completes.
In stead of increment/decrement the incomplete task count, a high-order bit
is flipped to mark and wait for the incomplete proxy task.
