DebugInfo: remove target-specific Frame Index handling for DBG_VALUE MachineInstrs

Frame index handling is now target-agnostic, so delete the target hooks

Machine Model: Add MicroOpBufferSize and resource BufferSize.
...
Replace the ill-defined MinLatency and ILPWindow properties with

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.

Remove the MachineMove class.
...
It was just a less powerful and more confusing version of
MCCFIInstruction. A side effect is that, since MCCFIInstruction uses
dwarf register numbers, calls to getDwarfRegNum are pushed out, which
should allow further simplifications.
I left the MachineModuleInfo::addFrameMove interface unchanged since
this patch was already fairly big.
