JDK-8329103 - assert(!thread->in_asgct()) failed during multi-mode profiling
Description
This is another manifestation of the same issue as in JDK-8329103. This time, however, production JVM crashes, not a debug build.
The reason is `in_asgct` flag is not reset correctly when AsyncGetCallTrace() is called recursively. The fix is similar to JDK-8329103.

From the 8u PR: An OpenJDK 8u specific bug has been created because: (1) in jdk8u, there is no assertion mentioned in the title of JDK-8329103; (2) the patch for JDK-8329103 does not apply to jdk8u, the fix needs to be implemented differently, although the idea is essentially the same.
