This implements the diagnostic option to abort VM early when compilation had failed. Similar patch
proved useful in Shenandoah work to capture performance bugs due to compilation skips early. There
is a list of tier1 tests that would fail if we turn this option on. Some of those failures probably
indicate testbugs.

Not really married to the name for the option, suggestions welcome. It is currently
AbortVMOnCompileFailure, as initially suggested by Vladimir. It seems to be in line with

Testing: hotspot/tier1, ad-hoc tests, jdk-submit (running)
