For each instruction itinerary class, specify the number of micro-ops each
...
instruction in the class would be decoded to. Or zero if the number of
uOPs must be determined dynamically.
This will be used to determine the cost-effectiveness of predicating a
micro-coded instruction.

lib/Target/SubtargetFeature.cpp asserts that the FeatureKV[] table be sorted
...
by its first field, but TableGen doesn't actually enforce creating it that
way. TableGen sorts the records that will be used to create it by the names
of the records, not the Name field of those records.
This patch corrects the sort to use the "Name" field of the record as the
sort key.

Rewrite tblgen handling of subtarget features so

it follows the order of the enum, not alphabetical.

warnings.
