Josh Poimboeuf 78be9facfb livepatch/klp-build: Add --show-first-changed option to show function divergence
Add a --show-first-changed option to identify where changed functions
begin to diverge:

  - Parse 'objtool klp diff' output to find changed functions.

  - Run objtool again on each object with --debug-checksum=<funcs>.

  - Diff the per-instruction checksum debug output to locate the first
    differing instruction.

This can be useful for quickly determining where and why a function
changed.
