Eduard Zingerman ef1ddbfcfa bpf: Track upper 32-bit register halves' liveness in compute_live_registers()
Extend compute_live_registers() to track upper and lower register
halves' liveness separately. This is mostly straightforward:

- use/def masks are extended to track 2 bits per register;
- compute_insn_live_regs() is updated to properly track these
  2 bits according to the instruction semantics.
