RegisterCoalescer: Do not look for regclass of IMPLICIT_DEF.
IMPLICIT_DEF is a generic instruction and has no (fixed) output register class defined. The rematerialization code of the register coalescer should not scan the instruction description for a register class. This fixes a problem showing up in test/CodeGen/R600/subreg-coalescer-crash.ll with subregister liveness enabled. llvm-svn: 229443
