shortcut to address space map
more adjustments to shortcuts
allow null AddrSpace pointer in raw baselist
holes in the space indices
almost working
GT-2873 decompiler, other, and overlays
GT-2873 added OTHER space to java sleigh compiler, fixed decompiler
exception
isOtherSpace method
isOtherSpace java, addressing code review comments
GT-2873 added null check in decompiler reset
GT-2873 code review changes
Read and write space_other tag in SLA files
Version number for .sla file
GT-2873 fixups after merge
GT-2873 renamed Sparc registers: OTHER->OTHERWIN, WINWSTATE->WSTATE
GT-2873 added option in AddressInput to control OTHER space visibility
GT-2873 OTHER space now global
GT-2873 fixing comments refering to decompiler code in BasicCompilerSpec
