==================== Summary ====================

Author: eem

Ancestors: Cog-eem.377

Include the labelsDictionary in disassembly decoration in processor simulators that want it.  This allows i.e. the ARMv8 simulator to identify two-word literals by tagging the labels dictionary when a pc-relative load is decorated.

Item was added:
+ ----- Method: CogProcessorAlien>>decorateDisassembly:for:fromAddress:labels: (in category 'disassembly') -----
+ decorateDisassembly: anInstructionString for: aSymbolManager "<Cogit>" fromAddress: address labels: labelDictionaryOrNil
+ "This is a hook to allow decoration to add values to labelDictionary to get better decoration of out-of-line literals.
+ It is only relevant to 64-bit out-of-line literal back ends, which currently means only ARMv8.  Hence the default
+ defers to the original mehtod, used in most classes."
+ ^self decorateDisassembly: anInstructionString for: aSymbolManager fromAddress: address!
