ART: Change IndirectReferenceTable

Change cookie structure to allow for more entries. Use a local
hole-count caching scheme. The design is driven by two
considerations. For one, the change is small and mostly local.
The other point is to still allow inlining of functions involved
with JNI transitions.

This change is in preparation for a resizable backing table for
"unlimite" local references.

micro_native tests show changes are in the noise.
