still lots of uglyness.
Maybe calls will come soon.
Fixing the return value of things will be necessary to make alpha work.

This seems useful from the original patch that added the function.  If there is a reason it is not useful on a RISC type target, let me know and I will pull it out

1. Use SubtargetFeatures in llc/lli.

2. Propagate feature "string" to all targets.

3. Implement use of SubtargetFeatures in PowerPCTargetSubtarget.

putting it into the constant pool.  This allows the isel machinery to
create constants that it will end up deciding are not needed, without them
ending up in the resultant function constant pool.
