69a86e4e23 The old getIndices has been deprecated, because it no longer works. It now
is named getIndicesBROKEN() and shall be removed when the codebase is updated
to not call it

200a435966 Eliminate most uses of the machine instruction vector for each LLVM instr,

working with machine instructions alone.
