add access bits to brp.vpn entries, use brp cache for put16 & put32

Browse Source 
added get32m & put32m: these always map
changed get32 and put32 to be inlined
changed mem[] references to MEM[] to allow experiments
tried using register for MEM pointer - not so great
tried using register for instcount - screwed up (very sluggish)
