[PATCH 17/25] objtool: Set insn->func for alternatives

From: Peter Zijlstra
Date: Mon Mar 18 2019 - 11:54:48 EST


In preparation of function attributes, we need each instruction to
have a valid link back to its function.

Therefore make sure we set the function association for alternative
instruction sequences; they are, after all, still part of the function.
