0113e4e3f2 Fix PR8828 by removing the explicit def in MovePCToLR as well as the pointless 
piclabel operand. The operand in the tablegen definition doesn't actually turn
into an MI operand, so it just confuses anything checking the TargetInstrDesc
for the number of operands. It suffices to just have an implicit def of LR.

a5c177e70a We need to pass the TargetMachine object to the InstPrinter if we are printing 
the alias of an InstAlias instead of the thing being aliased. Because we need to
know the features that are valid for an InstAlias.

This is part of a work-in-progress.

68e6beeccc Revert r124611 - "Keep track of incoming argument's location while emitting LiveIns." 
In other words, do not keep track of argument's location.  The debugger (gdb) is not prepared to see line table entries for arguments. For the debugger, "second" line table entry marks beginning of function body.
This requires some coordination with debugger to get this working. 
 - The debugger needs to be aware of prolog_end attribute attached with line table entries.
 - The compiler needs to accurately mark prolog_end in line table entries (at -O0 and at -O1+)

2da8bc8a5f Various bits of framework needed for precise machine-level selection 
DAG scheduling during isel. Most new functionality is currently
guarded by -enable-sched-cycles and -enable-sched-hazard.

Added InstrItineraryData::IssueWidth field, currently derived from
ARM itineraries, but could be initialized differently on other targets.

Added ScheduleHazardRecognizer::MaxLookAhead to indicate whether it is
active, and if so how many cycles of state it holds.

Added SchedulingPriorityQueue::HasReadyFilter to allowing gating entry
into the scheduler's available queue.

ScoreboardHazardRecognizer now accesses the ScheduleDAG in order to
get information about it's SUnits, provides RecedeCycle for bottom-up
scheduling, correctly computes scoreboard depth, tracks IssueCount, and
considers potential stall cycles when checking for hazards.

ScheduleDAGRRList now models machine cycles and hazards (under
flags). It tracks MinAvailableCycle, drives the hazard recognizer and
priority queue's ready filter, manages a new PendingQueue, properly
accounts for stall cycles, etc.
