rS346695: Remove p_code from struct proc.
Summary

Contrary to the comments, it was never used by core dumps or debuggers.
Instead, it used to hold the signal code of a pending signal, but that
was replaced by the 'ksi_code' member of ksiginfo_t when signal information
was reworked in 7.0.

Test Plan
  • compiled and booted amd64 and i386 kernels and ran ptrace_test under both
