[10] RFR: 8193699: AArch64 Fails to build after 8167372

[Rahul Raghavan]

Hi,

Request help to review the following fix proposal.

<webrev> - http://cr.openjdk.java.net/~rraghavan/8193699/webrev.01/

Related <jbs> links -
-- https://bugs.openjdk.java.net/browse/JDK-8193699
-- https://bugs.openjdk.java.net/browse/JDK-8167372
   - 'Add code to check for getting oops while thread is in native'
-- https://bugs.openjdk.java.net/browse/JDK-8191227
   - 'Unsafe handle resolution in ConstantOopWriteValue::write_on() / 
print_on() and LIR_Assembler::jobject2reg()'

Found root cause of 8193699 issue, as missing changes for aarch64 in 
'macroAssembler_aarch64.cpp',
similar to changes done for 8191227 before pushing 8167372 support.
So now fixed the issue of unsafe handle resolution in 
'macroAssembler_aarch64.cpp' with the usage of ThreadInVMfromUnknown.
Stuart Monteith confirmed build failure fixed with above proposed 
changeset and no new issues with testing.

Thanks,
Rahul
