Summary: The improvements to the LegalizerInfo discussed in D42244 require that LegalizerInfo::LegalizeAction be available for use in other classes. As such, it needs to be moved out of LegalizerInfo. This has been done separately to the next patch to minimize the noise in that patch. llvm-svn: 323669
