[ARM][ReachingDefs] RDA in LoLoops
Add several new methods to ReachingDefAnalysis:
- getReachingMIDef, instead of returning an integer, return the
MachineInstr that produces the def.
- getInstFromId, return a MachineInstr for which the given integer
corresponds to.
- hasSameReachingDef, return whether two MachineInstr use the same
def of a register.
- isRegUsedAfter, return whether a register is used after a given
MachineInstr.
These methods have been used in ARMLowOverhead to replace searching
for uses/defs.
