b6a638898a Increase SubtargetFeatureKV Value and Implies fields to 64 bits since some targets are getting very close to 32 subtarget features. Also teach tablegen to error when there are more than 64 features to guard against undefined behavior. rdar://9282332

5f54ce3473 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.

FU per CPU arch to 32 per intinerary allowing precise modelling of quite
complex pipelines in the future.

7c9a7728d9 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.

db01c8ba26 Rewrite tblgen handling of subtarget features so
it follows the order of the enum, not alphabetical.
The motivation is to make -mattr=+ssse3,+sse41
select SSE41 as it ought to.  Added "ignored"
enum values of 0 to PPC and SPU to avoid compiler
warnings.

4222d806fa Add an "implies" field to features. This indicates that, if the current
feature is set, then the features in the implied list should be set also.
The opposite is also enforced: if a feature in the implied list isn't set,
then the feature that owns that implies list shouldn't be set either.
