RFR: 8203353: Fixup inferred decorators in the interpreter

[Erik Österlund]

Hi,

All subsystems that the access API touches, except the interpreter, 
infers a set of decorators according to rules specified in 
accessDecorators.hpp. These are typically sane defaults for things like 
reference strength, memory ordering, as well as inferring that 
IN_HEAP_ARRAY is IN_HEAP, and IN_CONCURRENT_ROOT is IN_ROOT. The 
interpreter should do that too.
