RFR(M): JDK-8165496 assert(_exception_caught == false) failed: _exception_caught is out of phase

[Dmitry Samersoff]

Everybody,

Please review.

http://cr.openjdk.java.net/~dsamersoff/JDK-8165496/webrev.07/

Bug link:

https://bugs.openjdk.java.net/browse/JDK-8165496

Two separate flags, exception_detected and exception_caught, replaced
with one that changes it's state.

Assert assert(_exception_caught == false) and fix for JDK-8134434 are
removed.

Testing:
  1. Manual testing of instrumented hotspot
  2. Local ks with stress agent
  3. RBT ks with stress agent
  4. RBT hotspot_all
