RFR (S) 8212070: Introduce diagnostic flag to abort VM on failed JIT compilation

[Tobias Hartmann]

Hi Aleksey,

this looks good to me but I also prefer 'AbortVMOnCompilationFailure'.

Just noticed that the indentation in globals.hpp:2020 is wrong (also in some previous lines) and I
prefer a newline between flag definitions.

Best regards,
Tobias
