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

headers provide symbols outside namespace std and the LLVM coding standards
state that we should prefix all of them.

string of features for that target. However LTO was using that string to pass
into the "create target machine" stuff. That stuff needed the feature string to
be in a particular form. In particular, it needed the CPU specified first and
then the attributes. If there isn't a CPU specified, it required it to be blank
-- e.g., ",+altivec". Yuck.

Modify the getDefaultSubtargetFeatures method to be a non-static member
function. For all attributes for a specific subtarget, it will add them in like
normal. It will also take a CPU string so that it can satisfy this horrible
syntax.

Rollback changes r89516: Added two SubtargetFeatures::AddFeatures methods, which accept a comma-separated string or already parsed command line parameters as input, and some code re-factoring to use these new methods.

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.
