RFR: turn off critical jni

[Fedor Burdun]

Hi all,

Since aarch32 has no support critical jni entries (a most of required routines are unimplemented).
I would like to suggest to turn off this feature.

The idea it to switching off this flag in VM_Version::initialize()
although it is not the best place to do such things I can't find any better one.

The good assumption is to disable it in globals_aarch32.hpp,
but eventually CriticalJNINatives flag was not declared as platform dependant.

Moreover the flag UseBiasedLocking seems not to be turned off in despite of
confusing line "define_pd_global(bool, UseBiasedLocking, false);" in globals_aarch32.hpp

The test case that reproduces problem is in attachement (src.tgz), however it looks like it affects only jit-ed code.

Thanks,
Fedor
