- Added MCSubtargetInfo to capture subtarget features and scheduling
...
itineraries.
- Refactor TargetSubtarget to be based on MCSubtargetInfo.
- Change tablegen generated subtarget info to initialize MCSubtargetInfo
and hide more details from targets.

Add annotations to tablegen-generated processor itineraries, or replace them with something meaningful. I want to be able to read and debug the generated tables.

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.

Extend the instruction itinerary model to include the ability to indicate the def and use cycle for each operand. This additional information is optional, so existing itineraries do not need to be changed.
