  Log Message:
  -----------
  [lldb] [Process/FreeBSDRemote] Introduce mips64 support

Introduce mips64 support to match the legacy FreeBSD plugin. Similarly
to the legacy plugin, the code does not support FPU registers at the
moment.  The support for them will be submitted separately as it
requires changes to the register context shared by both plugins.

This also includes software single-stepping support that is moved from
the Linux plugin into a common Utility class.  The FreeBSD code also
starts explicitly ignoring EINVAL from PT_CLEARSTEP since this is easier
to implement than checking whether hardware single-stepping were used.
