update mca tests


As determined with `llvm-exegesis`.

Some of these look like typos/misunderstandings of the sched model td
spec:

- latency defaults to `1` when not set => Maybe we can avoid having a default ?
- problems with regexps not being anchored by default (XCHG matching CMPXHG)

Note that this is not complete, it fixes only the most obvious mistakes,
and only for latency (not uops).
