b460a33829 Revert r158679 - use case is unclear (and it increases the memory footprint). 
Original commit message:
    Allow up to 64 functional units per processor itinerary.

    This patch changes the type used to hold the FU bitset from unsigned to uint64_t.
    This will be needed for some upcoming PowerPC itineraries.

0076ad7eeb Sched itinerary fix: Avoid static initializers. 
This fixes an accidental dependence on static initialization order that I introduced yesterday.

Thank you Lang!!!

b7e0289fb3 misched: API for minimum vs. expected latency. 
Minimum latency determines per-cycle scheduling groups.
Expected latency determines critical path and cost.

fc992996f7 misched: Added MultiIssueItineraries. 
This allows a subtarget to explicitly specify the issue width and
other properties without providing pipeline stage details for every
instruction.
