   # HEAD: 2d3451ef1ef679ae496f8e335f4b1305885e8083 objtool: Simplify .annotate_insn code generation output some more

Address various objtool scalability bugs/inefficiencies exposed by
allmodconfig builds, plus improve the quality of alternatives
instructions generated code and disassembly.

 Thanks,

	Ingo
