Change how non-volatile register preservation is done in alien callbacks, with the aim of fixing callbacks on PowerPC, and to eventually eliminate assembly code from VM - Simplify calculation of offset in relocation table - Open-code %alien-callback - Remove magic_frame hack from context objects - Move magical return instruction from optimizing compiler backend into callback entry stub
