RFR: 8133951: Zero interpreter asserts in stubRoutines.cpp

[Vladimir Kozlov]

Insts sizes are set by CodeBuffer constructor which is called before 
StubGenerator_generate:

     CodeBuffer buffer(_code1);
     StubGenerator_generate(&buffer, false);

See CodeBuffer::initialize() and CodeSection::initialize(). So if 
nothing generated insts_remaining() should be code_size1 value. Why it 
is not?

Thanks,
Vladimir
