RFR: 8264166: OopStorage should support specifying MEMFLAGS for allocations [v2]

[Kim Barrett]

> Please review this change to OopStorage to allow the MEMFLAGS value for associated allocations to be specified when the storage object is constructed.  This allows a subsystem that needs an OopStorage object to associate its allocation with others for that subsystem in NMT tracking and reporting.
> 
> Testing:
> mach5 tier1.
> Manually compared NMT output before and after this change for a test that generated a lot of one particular OopStorage entries.
