- Shrink 'struct instruction', to improve objtool performance & memory
footprint.
- Other maximum memory usage reductions - this makes the build both faster,
and fixes kernel build OOM failures on allyesconfig and similar configs
when they try to build the final (large) vmlinux.o.
- Fix ORC unwinding when a kprobe (INT3) is set on a stack-modifying
single-byte instruction (PUSH/POP or LEAVE). This requires the
extension of the ORC metadata structure with a 'signal' field.
- Misc fixes & cleanups.
