Machine Model: Add MicroOpBufferSize and resource BufferSize.
Replace the ill-defined MinLatency and ILPWindow properties with
with straightforward buffer sizes:
MCSchedMode::MicroOpBufferSize
MCProcResourceDesc::BufferSize
These can be used to more precisely model instruction execution if desired.
Disabled some misched tests temporarily. They'll be reenabled in a few commits.

I'm introducing a new machine model to simultaneously allow simple
subtarget CPU descriptions and support new features of
MachineScheduler.
MachineModel has three categories of data:
1) Basic properties for coarse grained instruction cost model.
2) Scheduler Read/Write resources for simple per-opcode and operand cost model (TBD).
3) Instruction itineraties for detailed per-cycle reservation tables.
These will all live side-by-side. Any subtarget can use any
combination of them. Instruction itineraries will not change in the
near term. In the long run, I expect them to only be relevant for
in-order VLIW machines that have complex contraints and require a
precise scheduling/bundling model. Once itineraries are only actively
used by VLIW-ish targets, they could be replaced by something more
appropriate for those targets.
This tablegen backend rewrite sets things up for introducing
MachineModel type #2: per opcode/operand cost model.

Reapply "Make NumMicroOps a variable in the subtarget's instruction itinerary."
Reapplies r159406 with minor cleanup. The regressions appear to have been spurious.

Revert "Make NumMicroOps a variable in the subtarget's instruction itinerary."
This reverts commit r159406. I noticed a performance regression so I'll back out for now.

Make NumMicroOps a variable in the subtarget's instruction itinerary.
The TargetInstrInfo::getNumMicroOps API does not change, but soon it
will be used by MachineScheduler. Now each subtarget can specify the
number of micro-ops per itinerary class. For ARM, this is currently
always dynamic (-1), because it is used for load/store multiple which
depends on the number of register operands.
Zero is now a valid number of micro-ops. This can be used for
nop pseudo-instructions or instructions that the hardware can squash
during dispatch.

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.

Sched itinerary fix: Avoid static initializers.
This fixes an accidental dependence on static initialization order that I introduced yesterday.
Thank you Lang!!!

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

other properties without providing pipeline stage details for every
instruction.
