[PATCH tip/core/rcu 20/21] tools/memory-model: Allow herd to deduce CPU type

[Paul E. McKenney]

Currently, the scripts specify the CPU's .cat file to herd.  But this is
pointless because herd will select a good and sufficient .cat file from
the assembly-language litmus test itself.  This commit therefore removes
the -model argument to herd, allowing herd to figure the CPU family out
itself.

Note that the user can override herd's choice using the "--herdopts"
argument to the scripts.
