[PATCH] D29295: Move core RDF files from lib/Target/Hexagon to CodeGen

[Krzysztof Parzyszek via Phabricator via llvm-commits]

Multiple fixes to RDF, addressed comments.

Increased the scope of testing: created an extra post-RA pass that ran the RDF-based copy propagation and dead code elimination, followed by liveness recomputation (in a similar way to what HexagonRDFOpt.cpp does).  I manually checked "make check-llvm-codegen" failures on AArch64, ARM and PowerPC, and they seem to be caused by these optimizations modifying the code to a form not expected by the testcase.  In all those cases the code appeared to still be correct.
