      "message": "ART: Refactor SsaBuilder for more precise typing info\n\nThis patch refactors the SsaBuilder to do the following:\n\n1) All phis are constructed live and marked dead if not used or proved\nto be conflicting.\n\n2) Primitive type propagation, now not a separate pass, identifies\nconflicting types and marks corresponding phis dead.\n\n3) When compiling --debuggable, DeadPhiHandling used to revive phis\nwhich had only environmental uses but did not attempt to resolve\nconflicts. This pass was removed as obsolete and is now superseded\nby primitive type propagation (identifying conflicting phis) and\nSsaDeadPhiEliminiation (keeping phis live if debuggable + env use).\n\n4) Resolving conflicts requires correct primitive type information\non all instructions. This was not the case for ArrayGet instructions\nwhich can have ambiguous types in the bytecode. To this end,\nSsaBuilder now runs reference type propagation and types ArrayGets\nfrom the type of the input array.\n\n5) With RTP being run inside the SsaBuilder, it is not necessary to\nrun it as a separate optimization pass. Optimizations can now assume\nthat all instructions of type kPrimNot have reference type info after\nSsaBuilder (with the exception of NullConstant).\n\n6) Graph now contains a reference type to be assigned to NullConstant.\nAll reference type instructions therefore have RTI, as now enforced\nby the SsaChecker.\n\nBug: 24252151\nBug: 24252100\nBug: 22538329\nBug: 25786318\n\nChange-Id: I7a3aee1ff66c82d64b4846611c547af17e91d260\n"
