Cleanup dangling issues from 64bit merge
CkLocMgr still has some unnecessary or erroneous bits of code that were left over from the 64bit merge. At a quick glance:
- CmiUInt8 is still only used for chare arrays and isn't well documented
-The CkLocRec hash table is poorly hashed after switching the key from CkArrayIndex to CmiUInt8
-Some fault tolerance code still seems to be using CkArrayIndex where it shouldnt. See createLocal() in cklocation.C
-Since all records are now local, flushLocalRecs() and reclaimRemote(...) in cklocation.C may be no longer needed at all.
