    bfd: aarch64: Fix BTI stub optimization PR30957

    The instruction was looked up in the wrong input file (file of branch
    source instead of branch target) when optimizing away BTI stubs in

      commit 5834f36d93cabf1a8bcc7dd7654141aed3d296bc
      bfd: aarch64: Optimize BTI stubs PR30076

    This can cause adding BTI stubs when they are not necessary or removing
    them when they are (the latter is a correctness issue but it is very
    unlikely in practice).

    Fixes bug 30957.
