gh-104909: Split some more insts into ops (#109943)

Browse source 
These are the most popular specializations of `LOAD_ATTR` and `STORE_ATTR`
that weren't already viable uops:

* Split LOAD_ATTR_METHOD_WITH_VALUES
* Split LOAD_ATTR_METHOD_NO_DICT
* Split LOAD_ATTR_SLOT
* Split STORE_ATTR_SLOT
* Split STORE_ATTR_INSTANCE_VALUE

Also:

* Add `-v` flag to code generator which prints a list of non-viable uops
  (easter-egg: it can print execution counts -- see source)
* Double _Py_UOP_MAX_TRACE_LENGTH to 128



I had dropped one of the DEOPT_IF() calls! :-(
