CodeGen: Move LibcallLoweringInfo to be with RuntimeLibcallInfo
Eventually this will be program dependent state, so it should not
be part of TargetLowering. It's easiest to have this as part of
the analysis that will provide RuntimeLibcallInfo. In principle
we would also need this to more precisely refine the set of libcalls
that full LTO could trim based on the subtarget.
