Consolidate all alignment-related `cl::opt` definitions into `CommandLineOpts.cpp`, expose matching public members on `BinaryContext`, and populate them from `RewriteInstance::adjustCommandLineOptions` (and mirrored in `MachORewriteInstance`). Switch all readers in Aligner, BinaryEmitter, LongJmp, BinaryFunction and the use-old-text logs to `BC.*` instead of `opts::*`.
