47fe1b63f4 [RDF] Lower the sorting complexity in RDFLiveness::getAllReachingDefs 
The sorting is needed, because reaching defs are (logically) ordered,
but are not collected in that order. This change will break up the
single call to std::sort into a series of smaller sorts, each of which
should use a cheaper comparison function than the original.

080dd10f7d Move RDF from Hexagon to Codegen 
RDF is designed to be target agnostic. Therefore it would be useful to have it available for other targets, such as X86.
