[8u] RFR 8173373: C1: NPE is thrown instead of LinkageError when accessing inaccessible field on NULL receiver

[Vladimir Kempik]

Hello

Please review this backport of 8173373 for jdk8u.

The fix applied cleanly to jdk8, except one place:

in src/share/vm/c1/c1_LIR.cpp

I had to change

+    CodeStub* deopt = new DeoptimizeStub(info, 
Deoptimization::Reason_null_check, Deoptimization::Action_none);

to

+    CodeStub* deopt = new DeoptimizeStub(info);

The fix passes jprt and testcase.
