[8u] RFR 8212070: Introduce diagnostic flag to abort VM on failed JIT compilation

[Aleksey Shipilev]

Original RFE:
   https://bugs.openjdk.java.net/browse/JDK-8212070
   https://hg.openjdk.java.net/jdk/jdk/rev/b8c88c64abf0

This is surprisingly useful to follow-up on performance/functional failures. It was already 
backported to 11u. Let's have it in 8u as well. The patch does not apply cleanly to 8u, but that's 
for the better, because the patch for 8u is much more straight-forward:
   https://cr.openjdk.java.net/~shade/8212070/webrev.8u.01/

Testing: tier1 with/without the new flag; some interesting failures with the new flag!
